Question

A particle is travelling in a circle of diameter 15 metre calculate the distance covered and displacement when it completes two rounds ​

Answer 1

Answer:

Diameter of the Circular Path = 15 m. We know, Circumference of the Circular path will be the Distance covered by the Body in one Round. Thus, Distance is 660/7 m during two rounds. Reason ⇒ Body returns to the same point after the second Round, thus displacement will be zero.
