Question

A boy carrying a box on his head is walking on a level road from one place to another. The boy is doing no work.

• A. True
• B. False

Answer 1

The correct option is A True

The boy is walking i.e., displacement is in the horizontal direction, and the force acting on the box is due to the gravitational pull in the downward direction. So the displacement and the force are perpendicular to each other.

Hence, the work done is zero.
