Which one of the following statements for the work done by gravity on a body is NOT correct ?

  1. A. Work done is independent of the path followed by the body
  2. B. Work done depends only on the vertical distance separating the initial and the final position of the body
  3. C. Work done depends on the path followed by the body
  4. D. Work done is zero if the body is displaced horizontally to the force of gravity

Correct Answer: C. Work done depends on the path followed by the body

Explanation

Gravity is a conservative force, meaning the work done by it is independent of the path taken and depends only on the initial and final positions.
