Question

The potential energy of a boy is maximum when he is:

• A. standing
• B. Sleeping on the ground
• C. Sitting on the ground
• D. Sitting on chair

Answer 1

The correct option is A

standing

Explanation for the correct answer:

1. Potential energy:- It is the energy stored in an object by the virtue of its position.
2. It is the product of mass, acceleration due to gravity, and the height of the object. $P.E.=mgh.$
3. Potential energy is maximum when the height of an object is maximum.
4. Thus, the potential energy of a boy is maximum when he is standing.

Hence, option A is correct.
