Question

A student touches a rubber ball with a negatively charged plastic rod. How will the negative charges be distributed on the ball?(1 point)ResponsesOn the bottom of the ball’s surfaceOn the bottom of the ball’s surfaceEvenly distributed on the ball’s insideEvenly distributed on the ball’s insideEvenly distributed on the ball’s surfaceEvenly distributed on the ball’s surfaceOn the ball’s surface where the rod touches the ballOn the ball’s surface where the rod touches the ball

Answer 1

When a negatively charged plastic rod touches a rubber ball, the negative charges (electrons) from the rod will transfer to the ball. This will cause the ball to become negatively charged. The distribution of the negative charges will be influenced by the shape and grounding of the ball.

In this case, the negative charges will be:

Evenly distributed on the ball’s surface.

This is because charges tend to repel each other and will spread out as much as possible to minimize repulsion, resulting in an even distribution over the surface of the ball once the rod is removed.
