**1. Homework Statement**

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. Homework Equations**

E= -

E

**∇**V

**3. The Attempt at a Solution**

E= Q

E

**r**/4πε

_{o}R

^{3}= -

**∇**V

V

_{E}= - ∫

_{c}

**E**. d

**l**

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**= Q

**r**/4πε

_{o}R

^{3}to find V?
