Charge q 500icircfrac14c is distributed uniformly over the

Question

Problem: Charge Q=+ 5.00μC is distributed uniformly over the volume of an insulating sphere that has radius R = 5.00cm.

Part A: What is the potential difference between the center of the sphere and the surface of the sphere?

I need help to determine the potential difference between the center of the sphere and the surface of the sphere.
