Question
Which of the following is not an example of nonconservative force?
Correct Answer
Option B is the correct answer.
Detailed Explanation
Elastic force (spring force) is a conservative force because the work done depends only on initial and final positions and is recoverable. Friction, push-pull (applied forces), and tension are typically nonconservative as they can depend on path or dissipate energy.
Hint
Conservative forces have potential energy associated with them, like gravity and spring force.
