A sphere of radius R carries an electric charge Q, uniformly distributed inside its volume.
(a) Using the expression for the electric field given in the lectures, compute the electrostatic potential V (r) inside and outside the sphere.
E[/B] = -∇V
The Attempt at a Solution
E[/B] = Qr/4πεoR3 = -∇V
VE= - ∫c E . dl
But now I'm really unsure of how you get V from this? Because you can't divide by the gradient function... So do I integrate E = Qr/4πεoR3 to find V?
