What is the voltage at 5.00 cm from the center of a 1 cm diameter metal sphere that has a static charge of -3.00 nC? Remember that in a conducting sphere, the electric charge is uniformly distributed on the surface. Therefore, it produces an electric field that is also uniform. Then, the situation could be thought of as if the charge and the electric field were produced by a point charge.
a. -1.5x10^-11 V
b. -539 V
c. 6x10^-8 V
