Question

A body covers a one half of a circular track of radius r then the distance and displacement is

Answer 1

Answer:

distance is 2r

and displacement is 2r

Answer 2

Answer:

Distance and displacement covered by the body on half of circular track are πr and 2r

Step-by-step explanation:

When a particle covers half of a circle of radius r,

then displacement is =diameter = r+r=2r

and

The distance = half of circumference of circle

Circumference of circle=2πr

The distance =half of 2πr

                      =πr

Distance and displacement covered by the body on half of circular track are πr and 2r
