Question

A particle moves along a circular path of radius 'r' with uniform speed 'V'. The angle described by the particle in one second is ______.

Options

• V²r

• ${\displaystyle \frac{r}{V}}$

• Vr

• ${\displaystyle \frac{V}{r}}$

Answer 1

A particle moves along a circular path of radius 'r' with uniform speed 'V'. The angle described by the particle in one second is ${\displaystyle \underline{\frac{V}{r}}}$.

Explanation:

V = rω ${\displaystyle =r\frac{\theta }{t}}$

${\displaystyle \therefore \frac{\theta }{t}=\frac{V}{r}}$
