Question

A particle is moving in a circle of diameter 14m.Calculae the distance covered and the displacement when it completes 3 revolution

Answer 1

Answer:

Distance=132m

Displacement=0 (B'coz initial & final points are same)

Explanation:

Diameter-14m

Radius-14/2=7m

2$\pi$r

=2*$\frac{22}{7}$*7

=2*22

=44

=44*3

=132m
