Question

A particle is moving in circle of diameter 5m.what is distance and displacement after 3 rounds

Answer 1

Answer:

Distance traveled after 3 rounds is pi*15cm or 47.14cm. and the displacement will be zero.

Explanation:

First find the perimeter of the circle by 2*pi*r^2 (r=d/2)

multiply the answer by 3 as the particle takes three rounds and that becomes you distance.

Displacement is zero as both its starting and terminating points are the same
