Question

A particle is moving in a circle of diameter 5m. What is the displacement when it completes 1.5 revolutions ?

Answer 1

Hi.

Diameter of circle = 5 m

After 1.5 revolutions, it will move from point A to point B (See fig.). This is equal to the diameter of the circle. Hence displacement after 1.5 rounds = 5 cm.

Hope it helps.
