Answer 1

When a negatively charged plastic rod touches a neutral rubber ball, the negative charges (electrons) from the rod will transfer to the ball due to contact. This will cause the negative charges to redistribute throughout the ball.

The correct response is:

**Evenly distributed on the ball’s surface.**

Once the electrons are transferred, they will spread out across the surface of the ball, as like charges repel each other and they will seek to be as far apart as possible.
