4 0

Answer:

0

Explanation:

When the ball is going upward

The force mg is acting downward and the dispalcement is upward

So, the work done by the gravitational force is - mgh.

When the ball is going downward

The force mg is acting downward and the dispalcement is downward

So, the work done by the gravitational force is  mgh.

The total work done in entire trip is mgh - mgh = 0.
