Which one of the following is not a conservative force?

Options

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

Correct answer

A. Frictional force

Step-by-step solution

A conservative force is a force done in moving a particle from one point to another, such that the force is independent of the path taken by the particle. Gravitational force is an example of a conservative force, while frictional force is an example of a non-conservative force. Other examples of conservative forces are a force in elastic spring, the electrostatic force between two electric charges, and magnetic force between two magnetic poles.
