MCQ
Potential energy of a person is minimum when:
- APerson is standing.
- BPerson is sitting on a chair.
- CPerson is sitting on the ground.
- DPerson is lying on the ground.
✓
Answer
- Person is lying on the ground.
Explanation:
Potential energy of a body is defined as energy of a body due to its position in gravitational field.
In general, Potential energy = M × g × h where: h is the height above ground.
If the person will be lying on ground then it will have minimum height above the ground therefore potential energy of the person will also be minimum.
