The force a spring exerts on a body is a conservative forcebecause: a. a spring always exerts a force opposite to the displacementof the body. b. a spring always exerts a force parallel to the displacementof the body. c. the work a spring does on a body is equal for compressionsand extensions of equal magnitude. d. the net work a spring does on a body is zero when the bodyreturns to its initial position.

Explanation / Answer
If the net work done along a closed path is equal to zero thenthe force is conservative . So, The net work a spring does on a body is zero when the bodyreturns to its initial position
