A conducting sphere of 2.0 cm radius is charged with some unknown charge such that the electric potential 4.0 cm away from its surface is 100 Volts. What is the electric potential at the center of the conductor? If a proton is released at rest just outside the surface, what speed will it have when it's:
A) 2.0 cm away from the surface of the conductor?
B) Very far from the conductor?
