Question

a boy moves in a circular path of radius r. he makes a around along the circumference and stops. find the distance travelled and net displacement

Answer 1

A boy moves in a circular path of radius r. he makes a around along the circumference and stops.

Here, according to the statement

Circumference of the circle = 2πr,

Where 2 and π are constant and radius is r

Therefore, Distance travelled= Circumference of the circle = 2πr and net displacement = 0
