1. The problem statement, all variables and given/known data

A 2.04-mm-diameter ball bearing has 8.710×10^9 excess electrons. What is the ball bearing�s potential?

2. Relevant equations

3. The attempt at a solution

V = (1/4*pi*Eo) * (Q/r)

Eo = 8.85 x 10^-12

Q = 1.6x10^-19 * 8.71x10^9

r = 0.00204/2

V = 12308.78 V

Can someone tell me what I am doing wrong???
