Question

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

Answer 1

Answer:

distance covered is circumference of the circle

circumference of a circle = 2π r

C = 2 X 22/7 X 2R

C = 88/7 R

The body covered 2 rounds

distance covered = 2(88/7R)
