A box follows a zigzag path to reach from point A to B. The actual length of the path is 5 m and the length of the straight line joining the two points is 2 m. If a force of 5 N acts on the box then the work done on the box by the force (in joules) is ___ .

Solution

Work done = Force x displacement
Work is the product of force acting on the body and its displacement, so here displacement is 2 m as it is the shortest distance between two points. Hence work done by the force = 5 x 2 = 10 J.
