Question

A conductor is placed in an external electrostatic field. Theexternal field is uniform before the conductor is placed within it.The conductor is completely isolated from any source of current orcharge.
Which of thefollowing describes the electric field inside thisconductor?
It is in the samedirection as the original external field.
It is in theopposite direction from that of the original externalfield.
It has a directiondetermined entirely by the charge on its surface.
It is alwayszero.
The chargedensity inside the conductor is:
0
non-zero; butuniform
non-zero;non-uniform
infinite
