A conductor is placed in an external electrostatic field. The external field is uniform before the conductor is placed within it.The conductor is completely isolated from any source of current or charge.
PART A)
Which of the following describes the electric field inside this conductor?
It is in the same direction as the original external field.
It is in the opposite direction from that of the original external field.
It has a direction determined entirely by the charge on its surface.
It is always zero.
PART B)
The charge density inside the conductor is:
0
non-zero;but uniform
non-zero;non-uniform
infinite
PART C)
Assume that at some point just outside the surface of the conductor, the electric field has magnitude and is directed toward the surface of the conductor. What is the charge density on the surface of the conductor at that point?
Express your answer in terms of and .
