## Homework Statement

A metal ball with radius R = 0,6 m is charged with Q = 0.15 nC. Find the electrical field as function of the distance r from the center of the ball.

## The Attempt at a Solution

Gauss law:

Q = e

_{0}*E(r)*A = e

_{0}*E(r)*4*pi*R^2

which gives

E(r) = Q / e

_{0}*4*pi*R^2

I know that inside the ball, the field will be 0. But obviously this is not a function of r...Am I on the right track?
