Answer 1

When the ball on the left is pulled to the side and released, it will swing back and collide with the ball on the right.

Due to the conservation of momentum and the fact that the two balls have the same mass, when the moving ball (on the left) strikes the stationary ball (on the right), the left ball will come to a stop after the collision, and the right ball will swing to the right.

So, the correct response is:

The ball on the right will swing to the right.
