Two blocks "A" and "B" having masses 3kg and 4kg are raised to the same height from earth surface. The ratio of gravitational potential of "A" to that of "B" is
Correct answer: C. 1:1
- A. 3:4
- B. 4:3
- C. 1:1
- D. None
Explanation
Factual. Gravitational potential for an equipotential surface (one that is at same height) is same for all masses. Hence ratio will be 1:1

About Potential Energy
Potential energy is energy stored because of position or configuration, including gravitational potential energy near Earth's surface and elastic energy in a stretched or compressed spring. Questions use changes in potential energy and conservation of mechanical energy, while distinguishing a chosen reference level from an absolute zero of energy.
