A ball of mass m is thrown vertically up with an initial velocity so as to reach a height h. The correct statement is:
- Potential energy of the ball at the ground is mgh.
- Kinetic energy of the ball at the ground is zero.
- Kinetic energy of the ball at the highest point is mgh.
- Potential energy of the ball at the highest point is mgh.

Answer
Potential energy of the ball at the highest point is mgh.
Reason — At the highest point, the ball has maximum potential energy. The potential energy at a height h, above the ground is given by the formula mgh.
