the shell measuring the
strength of the electric field,
for which scenario will you
record the stronger electric
field strength?

In an electrostatic situation, the
electric field at every point within
the conductor
A. is constant, but not
necessarily zero.
B. is zero.
C. fluctuates based on the
motion of charged
particles on the surface
of the conductor.

The outer surface of a conductor with a hollow
cavity in it has a positive net charge of + 10 nC on
it. What should the be the charge of a particle
inserted into the cavity be to make the charge of
the outer surface of the conductor zero.
