Question

If a particle makes 1.5 revolution in a circular path of radius 2cm. The angular displacement is...??

Answer 1

the answer is
`theta=(1.5)(2pi)=3pi`

Explanation:

radius is `r=2`cm
angle of rotation per revolution is `2pi`
For 1.5 revolutions, the angle of rotation would be `theta=(1.5)(2pi)=3pi`
