Which one of the following forces is non-central and non-conservative?

Options

  1. AFrictional force
  2. BElectric force
  3. CGravitational force
  4. DMechanical force

Correct answer

A. Frictional force

Step-by-step solution

Non-conservative forces are dissipative forces such as friction or air resistance. These forces take energy away from the system as the system progresses, energy that you can't get back. These forces are path dependent; therefore it matters where the object starts and stops.
