Question

A body moves is a circle of radius ‘2R’ what is the distance covered and displacement of the body after 2 complete rounds?

Answer 1

Distance covered after 2 complete rounds
= 2 x circumference of a circle
Distance =2 × 2 π(2R) = 4π(2R)

After 2 complete rounds, the body comes back to its initial position,
so, displacement = 0
