A neutral metal 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.
This is because
1. the string is not a perfect insulator.
2. the number of electrons in the ball is greater than in the rod.

4. the ball becomes positively charged by induction.
