a body revolves a stone tied to a string 50 cm. so, radius of circle made by stone tied to a string is r = 50cm or 0.5m
we have to find distance and displacement covered by the stone in completing one revolution.
after one revolution
final position = initial position
so, displacement = (final position - Initial position) = 0
distance is the length covered by particle. so, distance after one revolution = circumference of circle of radius r = 0.5m
= 2π r = 2π(0.5) = π m
