Coulombs law: Rectangle with four charges on corners to find net force on one charge.

[@edvargas3105]

Excellet, clearly and very organized explanation of Coulumbus law. Thanks!!!

[@Ivan-go8yk]

Splendid... Very calmly and precisely explained! Thank you so much ...💙

[@jaynawa5905]

Thank you so much!

[@edhojilla6816]

You put so much effort on your videos, i hope u help more students like me. Thank you

[@jaynawa5905]

Thanks, Ed. Wish you all the best.

[@dde335]

i (someone else might've too) found during the video that you missed to square the radius (0.05), thx for such clear explanation though, i really appreciate it.

[@jaynawa5905]

You are correct. I made a note of that in video description. Thank you.

[@iftekharalam4024]

Appreciate this man

Please can you explain this question to me Four point charges are arranged at the corners of a rectangle as shown below.If q1=-3μc,q2=-5μc,q3=13μc and q4=-15μc,find the net force on q1 due to the other three charges.

Jay, I'm making a 2 minute video that shows how to do a physics charged particles problem with a spreadsheet. This video is a good example problem for me to use. Can I use 2 screenshots (problem layout and answer) of this video in my video? Thanks, Arthur Hebert.

[@jaynawa5905]

Yes. Please include in your screen shots my KZbin channel name either by saying it or by writing. Thanks for asking and best of luck.

Thank you sir

[@angelikanepomuceno5794]

Do you have an example if it is a parallelogram and not a rectangle?

[@jaynawa5905]

Sorry, I don't at this time. Parallelograms will be more challenging at this level. More trigonometry at the beginning and more vector analysis at the end. It also depends on how much info you have about the dimensions of the parallelogram, so each problem will be a bit different. Sorry I couldn't be much of a help at this time.

[@vincentjoserivasferrer8732]

Excuse me Sir, what can I do if, in a rectangle ABCD, form by 4 charges like your example I need to find the value of one of the charges. The other charges, and the distance between them are gave.

[@jaynawa5905]

Hi Vincent. I am assuming you also know the force (or not force). If so, your solution should begin where mine in the view ends, then trace back all the way till you find the value of the unknown charge. This will not be a simple thing to do, it will require some algebra.

[@vincentjoserivasferrer8732]

@@jaynawa5905 Thanks for answering me, in fact I don't know the force nor lacking of it. In that case my problem can still be solve ?

[@jaynawa5905]

@@vincentjoserivasferrer8732 That will be difficult to tell. But most likely not. You will need to know the force (or net force).

@@jaynawa5905 Maybe, my teacher forgot to put that ítem. Thanks a lot again, I hope you are going to be very good.!!

[@nadeemkhan4392]

Sir please give me fast reply ...you put the value of r 0.05 which is false the value of r should be the squre root of 0.05 am i right??

[@jaynawa5905]

r squared = .05 m squared, and that's what you need to plugin for Coulomb's law in F14, so this is correct. That being said, I missed squaring the unit in the graph (hypotenuse squared), the unit should be m squared, not m only.

I am using Wacom 360. You can record and edit the video using any video recording and editing free platforms. I used Camtasia.

Please my teachers formula is different from yours there is like an i and j for magnitude in this equation

Sir when 4 point is (00 ) , then how can we find net force on D by vector form

[@jaynawa5905]

Hi Satyam, could you please give me more details about your question? I will be happy to help you.

[@SatyamKumar-yz6vd]

Yes sir, Let a square ABCD sides 2m, 4m resp. Find the force on the charge placed at D point. Sir this question is based on vector law of coulomb law

[@jaynawa5905]

@@SatyamKumar-yz6vd If I understand your question correctly, here is what I will do, please go to min10:00 in the video. Then write forces in terms of unit vector notation. F14 = 4.83 i -2.4 j, F24 = 15.5 j, and finally F34 = 7.86 i (where i and j are unit vectors. Add all these vectors algebraically, the result will be your Net force in vector form. Use Pythagorean Theorem to find the magnitude and tan theta inverse to find the angle. I hope this helps.

[@SatyamKumar-yz6vd]

Sir on ABCD, can we make coordinate. Plz sir guide me For this I shall heartly thankful ...
