A neutral ball is suspended by a string.
A positively charged insulating rod is placed
near the ball, which is observed to be attracted to the rod.
Why is this?
1. The ball becomes negatively charged by
induction.
2. The string is not a perfect conductor.
3. The number of electrons in the ball is
greater than in the rod.
4. The ball becomes positively charged by
induction.
5. There is a rearrangement of the electrons
in the ball.
