Question

A particle is moving around a circular path with uniform angular speed $\left(\omega \right)$. The radius of the circular path is $\left(r\right)$. The acceleration of the particle is

• A. $\frac{{\omega }^2}{r}$
• B. $\frac{\omega }{r}$
• C. $v\omega$
• D. $vr$

Answer 1

The correct option is C $v\omega$

Centripetal acceleration, $a_r=r{w}^2$

Using $v=rw$

$⟹a_r=vw$
