Sir...🙏🏼thankyou so much..i was struggling with this question...now my concepts are clear ...right from the bottom to the top😀

E.ds = q/epsilon

Mei toh ds area hai gaussian surface ka
And jo q hai woh hai total body ka. ..

But aapne q nikalne k time only gaussian surface( radius= r ) tak ka volume se volumetric charge density ko. Multiply kyu kiye ??
Ye toh volumetric charge density × volume of whole atom ( radius = R ) tak hona chahiye na ..

Can you please tell which pen you are using

[demonhunter]

Nice explanation sir.
But sir I have doubt how do you say that ds & E are same direction?

Sir ncert mein electric field ka kaun sa formula use kiya gya r<R ke case mein

[gurlinkaur]

Thanks a ton sir..if u weren't there...ncert would horrible for me

Charge density constant Kaise Rahega vah to uniform Rahega na
