A box is pulled with a force of 25 N to produce a displacement of 15 m. If the angle between the force and displacement is `30^(@)`. Find the work done by the force ?

Explanation

A force is said to be a conservative force if the work done by or against the force in moving the body depends only on the initial and final positions of the body and not on the nature of the path followed between the initial and final positions. A force is said to be non - conservative if the work done by or against the force in moving a body depends upon the path between the initial and final positions.
