WBCS.LIVE practice question

Which of the following is not a conservative force?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Gravitational force
  2. Frictional force
  3. Electrostatic force
  4. Magnetostatic force

Correct answer and explanation

Correct answer: Frictional force

Explanation: āœ… Correct Answer: B) Frictional force šŸ“š Explanation: A force is called conservative if the work done by it is independent of the path taken, like gravity. Frictional force is 'non-conservative' because the work done against it depends on the length of the path. The energy used to overcome friction is dissipated as heat and cannot be recovered. Therefore, friction always leads to a loss of mechanical energy in a physical system.
