A body moves on three quarters of a circle of radius r. The displacement and distance travelled by it are:
A. displacement = r, distance = 3r

B. displacement =r, distance =

C. distance = 2r, displacement =

D. displacement = -, distance =

Answer :

From the diagram,

Circumference =

× Circumference =



Distance = Total path covered by the body

= × Circumference

= =


Displacement = Shortest Distance (Straight line) AB



= r

Hence, option B is correct.
