[@teachermichaelmaalim6103]

Splendid video. 4:10 Polite clarification. 😊😊😊Although Coulomb's constant kE is called Coulomb's constant because it is found within Coulomb's law, he is not the one who determined the value 8.9876x10^9 which we use today under the SI Units. The numerical value of Coulomb's constant depends on the (arbitrary) units of measure you select for force, distance and charge. The value when using the SI Units of newtons [N], metres [m] and coulumbs [C] would be different when using other units. A clearer name would be 'the Constant in Coulomb's Law' rather than 'Coulomb's Constant'.

u r reallly a excellent teacher i appreciate u

Your way of teaching is really unique... I got through many videos then finally i got to see your video and finally i m like *,oh i got it!!*

Thanks!

[@TheDenisemudge]

So glad we found this example! Thank you!

[@upandatom]

Denise Mudge I'm glad you found it helpful :)

[@TheFlyingGoatP]

Thank you for your video. You will be a good teacher. Keep it up. Actually F = (k x |q1| x |q2| ) / r^2 . The equation is to calculate the magnitude of the force. It's must be the absolute value of the charge. If we don't use the absolute value, the one charge is positive and the other is negative we will have negative force. And it's wrong, we don't have negative magnitude force, but we may have forces in negative direction.

[@upandatom]

great thanks for the correction!

[@m.rachid.lyaktini9193]

Thank you for correcting that mistake. F is always positive. Even she was excellent at explaining things. She successfully made things easier. I like her.

[@masterdjon]

Phat Phan : I would just like to add a small thing. In reality, a force is directional: a vector. Having a negative force only means to reverse the direction of the force. So, yeah, the force value can not be negative unless you consider it as a vector. Stating that, we have to know and remember the "size" of the force is never negative.

[@teachermichaelmaalim6103]

A negative force is attractive (pulling the objects together to reduce distance). A positive force is repulsive (pushing the objects apart to increase distance).

And after a huge search, I found this most complete video explaining about Coulomb's Law. I've Just skipped to example because I don't have too much time to study. Thanks a lot Jade.

[@upandatom]

no worries! glad it helped :) but if you wanna understand the theory and intuition of the equation better it might be helpful to watch the full video. You'd be surprised how much understanding a formula helps. But when I was doing my undergrad I only ever looked at the solution to examples as well so I guess I can't talk lol

[@nirmalaekka242]

I really want a teacher like you☺️

[@overlordprincekhan]

Hey Jade. yesterday I've seen your channel & I have loved all of these great explanation. Could you please answer to a question on this similar topic I've in my mind? As, you went to the explanation, you actually saying was that the electrons carrying energy. So, a coulomb has 6.24 x 10^18 electrons carrying 1 joule is called a volt. That means each of these electrons contain 6.24 x 10^-18 Joules. So, the question is, what's the maximum capacity of energy per single electron? I would be pleased if you've answer my question

[@tomlaight]

Given that the example question asks for the size (magnitude) of the electrostatic force, am I correct in thinking that the sign of either charge is unimportant? Could have two +ve charges, two -ve charges or one of each and the force's magnitude would stay the same, just the direction would change?

[@coreyyoung8140]

this is a nice video thx for the help and btw I got an 89 on my test from this. One day everybody will see how great you are.

[@mansoorabdulrhman2613]

For which class this

[@AllYourMemeAreBelongToUs]

She’s gotten much better.

[@bimblinghill]

From the way the example was worded, I don't think you can infer that the charges are equal or positive, but it doesn't really matter. The question just asks for the size of the force but doesn't specify whether its attractive or repulsive. The answer will be the same whether there are 2 negatives or two positives (repulsive force in either case), or if they are both different (so the force will be attractive. The answer to the question is just a number, there is no direction specified, so it will be the same whichever combination of charges you have.

[@SteveRaynerMakes]

But what is this constant k, where does that number come from? Is it some property of the environment? I mean the speed of light is a constant right? but it's different in air or water. So would this constant k change if the environment changed? For example if we vary the temperature or pressure.

[@trevorpsy]

You're a wonderful teacher! I'd love to hear you explain Maxwell's Equations, or have you done this already?.

Hi! I use camtasia for mac to do the editing (although I wouldn't recommend it, it's not great), and I do the drawings and writing using this app on a samsung galaxy tablet called s note. It comes with the tablet.

[@ShareInfos516]

Thanks for the video. Why the q1 and q2 have equal charge on the calculation?

is that the force of each charge on each other?

yes

Hi ma'am, according to my physics teacher , writing in scientific notation the valu of the number must be greater than 1 but less than 10 so wht is it your distance has a value of 150? it supposed to be 1.5?

[@markkeith9055]

Why oh why is it just like gravity?

[@michaelsommers2356]

+Mark Keith _"Why oh why is it just like gravity?"_ It isn't. Gravity has a negative sign in front of it: electric charges of the same sign repel, while masses of the same sign (which means all masses that we know of) attract.

[@sobianiaz30]

Yeah. Force of gravitation F=(G×m1×m2)/r^2 Where G = 6.673×10^11 N m^2 kg^-2

Jade, thank you so much for the generosity reflected in this awesome series of videos! In that spirit I would like to ask you about your platform. Specifically how do you add the graphic layer so that we can see notes and formulas added to the video of you speaking? I would appreciate any and all details; and if you have already explained it, please just give me a link and I will learn. I want to emulate your approach but focus on the topic of Measurement Uncertainty. Thanks for helping to make the Web a better place! Stephen

[@upandatom]

+tpuryearable Thank you Stephen! I'd be happy to answer any questions you have about producing similar videos. I've changed my style and software now, but when I made this video I was just using "S note" on a samsung tablet to write the notes. I was screen recording as I was writing, and then imported it into a video editing software called "camtasia" (but pretty much any video editing software will do). I just placed it over the footage of me talking and adjusting the timing so the notes would match what I was saying, and used a "keying" tool to get rid of the background color of the notes. I'd be happy to explain more if you like.

[@fahimal-huq6867]

THANKS A LOT.

[@Bob-lo1ob]

first of all hi and i have a Q why is the distance between the charges is given in Square what the logical answer for the distance separating them to be Squared `

[@upandatom]

Hi. Imagine the force around a charge like a sphere. The force some distance away from the charge = the force at some radius of the sphere. The surface area of a sphere is 4.pi.r^2, so the further out we measure a force from the charge, the more the surface area will increase proportional to the square of the radius (as 4 and pi are constants). So imagine the force more like the surface area of a sphere than as a point. The force needs to dilute as the surface area increases, and the surface area increases when the radius/distance increases. Let me know if you have any other questions :)

[@koroashisenjo]

Thank you maam!

hey why electrostatic force is directly proportional to size of charges.

[@upandatom]

It's like gravity, the larger the mass of an object, the larger the force it exerts on another object. Here, the larger the magnitude of the charge, the larger the force it can exert.
