हिन्दीConsider the following statements regarding conservative forces: (A) A force \( F(x) \) is conservative if it can be derived from a scalar potential function \( V(x) \) via \( F(x) = -\frac{dV}{dx} \). (B) The work done by a conservative force depends strictly on the particular path taken between two points. (C) The total work done by a conservative force in a closed path is zero. (D) Friction force between two rough surfaces is an example of a conservative force. Choose the correct answer from the options given below:
Correct answer · Option 1
(A) and (C) only
Explanation
Statements (A) and (C) are correct definitions of a conservative force. (B) is false as work is independent of path, and (D) is false as friction is non-conservative.
