Question

A boy after going around a circular track of radius ‘r’ comes back to the starting point. What is the displacement of the body?

Answer 1

The boy ran around a circular track which means the initial point and final point are same.

So there won’t be any displacement as the displacement is the difference between the initial and final points.

Displacement=(xfinal-Xinitial)

As the xfinal and xinitial are same we cannot determine the displacement.
