हिन्दीConsider the following statements regarding the concept of potential energy: (A) Potential energy is the 'stored energy' possessed by an object by virtue of its position or configuration. (B) Stretched bow-strings and compressed springs possess potential energy. (C) Readjustment of dislocations along fault lines in the Earth's crust releases stored potential energy, causing earthquakes. (D) For an object at height \( h \) with potential energy \( V(h) = mgh \), the gravitational force is given by \( F = +\frac{dV}{dh} \). Choose the correct answer from the options given below:
Correct answer · Option 1
(A), (B) and (C) only
Explanation
Statements (A), (B), and (C) are correct descriptions of potential energy. Statement (D) is incorrect because conservative force is the negative derivative of potential energy: \( F = -\frac{dV}{dh} \).
