1. The problem statement, all variables and given/known data 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. 2. Relevant equations E = -∇V 3. The attempt at a solution E = 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?
