The ball on the right will swing to the right.
The ball on the right will swing to the right.

Both balls will swing to the right.
Both balls will swing to the right.

Both balls will swing to the left.
Both balls will swing to the left.

The ball on the left will stop, and the ball on the right will remain still.

Answer 1

When the ball on the left swings back and collides with the ball on the right, the collision will cause the ball on the left to stop (or at least slow down significantly), and the ball on the right will swing to the right. This is due to the conservation of momentum and energy in elastic collisions between two objects of equal mass.

So, the correct response is:

The ball on the right will swing to the right.
