We start with a hollow, conducting sphere that is initially uncharged. We place a positive
charge
1 + q
inside the sphere as shown. We then place a second positive charge
2 +qnear,
but outside, the sphere. Which of the following describes the net electric force on each
charge?
The net force on
1 + q
is zero
because of Gauss’s Law
The net force on
2 + q
is not zero
because of polarization
A. There is a net electric force on
2 1 + + q q but not on .
B. There is a net electric force on
1 2 + + q q but not on .
C. Both charges feel a net electric force with the same magnitude and in the same
direction.
D. Both charges feel a net electric force with the same magnitude but in the opposite
direction.
E. There is no net electric force on either charge.
