Potential Energy & Equilibrium question from JEE Main 2025 (28 Jan, Shift 1)

Q4JEE Main 2025 · 28 JAN · SHIFT 1Medium

Potential Energy & Equilibrium

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R\mathbf{R}

Assertion A: In a central force field, the work done is independent of the path chosen. Reason R: Every force encountered in mechanics does not have an associated potential energy. In the light of the above statements, choose the most appropriate answer from the options given below

Show answer and solution

Answer: (b)

  1. A: a central force F(r)r^F(r)\hat r is conservative, so its work is path-independent. True.
  2. R: forces like friction have no potential energy. True.
  3. R talks about non-conservative forces, so it does not explain A.
  4. So the answer is (b).
