Question

A particle is moving along a circular track of radius 1 m with uniform speed. Find the ratio of the distance covered and the displacement in half revolution.

• A. 1 : 1
• B. 0 : 1
• C. $\pi :1$
• D. $\pi :2$

Answer 1

The correct option is D $\pi :2$

$Distance=\pi \ast R=\pi$ $displacement=2\ast R=1\ast 2=2$

therefore the ratio the distance covered and the displacement in half revolution$r=\frac{\pi }{2}$
