The electric potential at the surface of a charged conductor
a. is always zero.
b. is always independent of the magnitude of the charge on the surface. c. may be set equal to zero by adding an appropriate constant to the potential at all points of space. d. is always such that the potential is zero at all points inside the conductor.
e. is always such that the potential is always zero within a hollow space inside the conductor.
Question 2
The electric potential inside a charged solid spherical conductor in equilibrium
a. is always zero.
b. is constant and equal to its value at the surface. c. decreases from its value at the surface to a value of zero at the center.
d. increases from its value at the surface to a value at the center that is a multiple of the potential at the surface. e. is equal to the charge passing through the surface per unit time divided by the resistance.
