Physics · WORK, ENERGY AND POWER
हिन्दीGiven below are two statements: Statement I: The concept of potential energy can be validly defined for any arbitrary force, including frictional and viscous forces. Statement II: Gravitational potential energy \( V(h) \) of a body near the Earth's surface satisfies the relation \( F = -\frac{dV}{dh} \), where \( F \) is the gravitational force. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 4
Statement I is incorrect but Statement II is correct.
Explanation
Statement I is incorrect because potential energy is defined only for conservative forces where work gets stored up. Statement II is correct because the gravitational force is the negative derivative of gravitational potential energy.
