Find the average velocity when a particle complete the circle of radius 1 m in 10 sec .

A
$2 \mathrm{~m} / \mathrm{s}$
B
$3.14 \mathrm{~m} / \mathrm{s}$
C
$6.28 \mathrm{~m} / \mathrm{s}$
Correct answer
D
zero

Solution

When particle completes one revolution in circular motion, then average displacement travelled by particle is zero. Hence, Average velocity $=\frac{\text { average displacement }}{\Delta \mathrm{t}}=\frac{0}{\Delta \mathrm{t}}=0$

Hence, the correct answer is option: 'D'.
