A conducting sphere of radius 0.01 m has a charge of 1.0 × 10–9 C deposited on it. The magnitude of the electric field in N/C just outside the surface of the sphere is
The Attempt at a Solution
I tried the first equation and got 90000, but the answer is 900. I am racking my brains here trying to understand how to find the answer. Its seems simple enough, I am probably just missing a step, can anybody point to what I am doing wrong.
