## Homework Statement

The electric field at the surface of a charged, solid, copper sphere is 4200 N/C, directed toward the center of the sphere. The sphere has a radius of 0.190 m.

What is the potential at the center of the sphere, if we take the potential to be zero infinitely far from the sphere?

## Homework Equations

The potential is the same outside/insider right so that leaves:

[tex] V_{surfrace} = \frac {q} {4*pi*(8.85*10^{-12})*R} [/tex]

## The Attempt at a Solution

[tex] V_{surfrace} = \frac {4200*10^{-19}} {4*pi*(8.85*10^{-12})*0.190} [/tex]
