Pablo Brock · Answer 1

It is strongly attracted.

Explanation:

The rod is a conducting, it means that the charges are moving freely. So, when the ball is brought near it, the charges will move in response to the negative charge of the ball, to repulse to it, then they move from end B. It means that end A will be positively charged, the opposite of the ball, so they will be strongly attracted.
