These videos are the only way I am getting through my Physics 2 class. Thank youuuu!!!!

[@gamzekoyuncu]

I FINALLYYY UNDERSTANNDDD! your steps before giving the exact formula helps me get the idea clearly. Thank you a lot. I listened to the class, and searched for many videos on youtube but the way of your teaching is admirable. Precise and concise. YOUU ARE THEEE BEEESSTTT!!

[@elijahmoonblackwell9585]

Don't know why this popped up in my recomended.....but hey now I know stuff

[@PhysicsBro-xb8qx]

god wanted you to check out his videos

[@AmanSharma-e4x9j]

Or we can say AI wanted you to watch this video

[@koraycetin1229]

U are the god of universal teaching committee

[@puchkivlogger2722]

Very very helpful.... Pls do more on physics

[@kimfretzietunod2915]

plzzzz you've helped me so much in my entire high school years. I can't thank you enough. BUT THANK YOU

[@andryapimentel2373]

This explained Gauss' Law amazingly! Thank you! I think I am ready for my exam! :D

[@ronalds271]

He is the best science teacher.

[@rendanimakhavhu794]

Thank you so much. Hope GOD really makes your life better and easier than how you made mine. Thank again

[@quincyfinnley2653]

a trick : you can watch movies at flixzone. Me and my gf have been using them for watching a lot of movies during the lockdown.

[@landynlondon7474]

@Quincy Finnley Yup, been using Flixzone for years myself =)

[@ethangordon3935]

Why do you replace charge Q with the volume charge density at 8:00 , is it because you don't have a point but a whole sphere for charge and the radius is outside your Gauss circle inside the sphere?

[@overpredor3412]

These ticking sounds are perfect ❤

[@baselalkhooly3502]

for the equation he gave on 9:50, when i apply it to part a why doesnt it give me the same answer?

[@nyambegivenlinyotwa26]

thanks man am getting good grades in my physics....keep it up

[@jeonghyunyoo7430]

so much better than my prof, thank god

[@sofealadera6246]

I like all your vids. Keep it up bro!

[@patisthegreatest]

Thanks for the 18 points, king.

[@MBoy2000_]

you are literally a life saver, thank you so much

[@josemuygay8851]

this vids are the only reason why its feasible for me to study last minute and still do decent

[@Somweezey]

Hi there! I am having trouble with a similar question and was wondering if you could help? The only difference is that the inside of the sphere is a dielectric medium permittivity Epsilon. How would I go about working with that? do I just replace epsilon_0 with epsilon? Many thanks!

[@loganblanc3864]

That is what I would do if I encountered that problem

[@abhishekbhattacharjee4639]

Yeah

[@ragemamba5548]

does the density always be positive? even if the sphere has a negative charge?

[@arielcampos2008]

great video, thanks

[@ozzDeveveloperOpenForWork]

question a and b are the same so you can use both formula doesn't matter?

[@Tamoor622498]

What is there is a charge in the cavity of an insulator?

[@jdextlab]

Tamoor 622498 is it the point charge

[@BankruptGreek]

which metals have E=0 in them and which ones don't?

[@xOxAdnanxOx]

the E is 0 inside any material that allows the flow of electric charges ( conductors)

[@zehrademirhan600]

thanks very much it is really helpful

[@williammackey7243]

there are a few patent pages and wiki pages that talk about using radiation to increase charged particle density in a region, I am trying to find out why or what the purpose of increasing the charged particle density of the sky above my county, can you help me with this?

[@sarkersaadahmed]

2:41 it can be wrong so for gauss law, take the inner surface gausds law and outer surface gauss law, assume the volume of chunk charge as dV and the chunk charge itslef as dQ. dQ / dV = rho so dQ = rho*[dV] then to find total charge, integrate the dQ to Q and intgegrade the surface area [dV] to volume

[@roaahedaya1779]

If I am not mistaken inside the insulating sphere, charges are disturbed inside the volume of the sphere and they are not on the same line so the distance between them and the Gaussian surface won't be equal so the electric field won't be equal. I am quite confused thank you in advance

[@abhishekbhattacharjee4639]

Roaa Hedaya assuming charges are distributed equally I think

[@magneticocampo7761]

can you help me with a question of particle loaded which is abandoned in the center of a sphere that had a conical piece removed. A particle is abandoned inside the conical hole and gains speed. the particle is positively charged and the sphere is positively charged to the surface. you could make a video just by explaining the electric force versus distance graph so that I can calculate the work when the particle is expelled. or send your email to me to send the question.pls

[@danieljohnsopardenilla997]

For part a, wouldn't the positive electric field coming from the charges outside of the Gaussian surface counteract the positive electric field coming from the charges inside of the Gaussian surface, reducing the net electric field 1.5m away from the center of the sphere?

[@carsonkelly4052]

appreciate the help but i’m seriously about ready to drop engineering because of this class and calc 2. I can’t take it anymore i feel like a failure.

[@BabaYaga-bf4iv]

Why is Q enclosed = Q total × (V of gaussian surface/ V of sphere)?

[@mutaumayumbelo1233]

At 2:32 where is 4/3π coming from?

[@TheLostEngineer19]

The volume of any sphere is 4/3Pi * r^3

[@Chemicalevent]

this is so helpful

[@Sedonapass]

WHY is it sometimes we use 4PIr^2(area) and sometimes 4/3PIr^3(volume)?

[@brandnew8004]

Area = circle Volume = sphere These are different shapes and have different formulas

[@sean2606]

there is a beautiful derivation of this google it

[@vietnamsciencetoylab5846]

Why is it 4pi.r^2 not pi.r^2 ?

[@tesnimeboulfoul2273]

@@vietnamsciencetoylab5846 because it's a sphere not a circle

[@talebglazeit1935]

i love this man!!!

[@rochehoniball]

Why do some sources say the electric field inside a conductor is 0 but others say the electric field inside is kqr/R^3???

[@beepboopbot3276]

Have an ap physics c test tomorrow on this stuff 😫

[@coffee_bean__]

Are we ignoring relative permittivity (Er)?

it is a constant.

thanks again bud!

[@selinylmaz3069]

I can't understant that why we are using volume for insulating sphere? We are using surface for conducting sphere. What is the difference? So confusing

[@easymoney6576]

we use surface for conducting sphere because the charges are on the surface but in insulating surface the charge is uniformly distributed inside the volume

[@selinylmaz3069]

[@dayronbig585]

how is Q enc= QTxVg/Vs??? help please!! :)

[@kassemhassan1490]

you only want the charge in the gausses volume. think of it as a percentage , the vg is the value over 100% AKA vs

[@caalphaan]

Is there a reason why cant we use the standard formula for an electric field E = Kq/r^2 ?

[@caalphaan]

Wait I just realized its distributed evenly throughout the volume rather than being a point charge.
