A small metal ball is given a negative charge, then brought near (i. e., within about 1/10 the length of the rod) to end A of the rod ) What happens to end A of the rod when the ball approaches it closely this first time?
a. It is strongly repelled.
b. It is strongly attracted.
c. It is weakly attracted.
d. It is weakly repelled.
e. It is neither attracted nor repelled.

Option B, it is strongly attracted

Explanation:

A Test Charge Determines Charge on Insulating and Conducting Balls, and the points made regarding conductors, it can be ascertained that in conductors, the electrons are free to move about. This means that when a charge is brought near to a conductor, the opposite charges all navigate to the sharpest point closest the charge and a strong attraction is created.

This shows that the rod will be strongly attracted. The density of the charges on the rod is mostly concentrated at the sharpest point.
