Question

A particle moves along a circular track of $6m$ radius such that the arc of the circular track covered subtends an angle of ${30}^o$ at the centre. The distance covered by the body is

• A. $\pi m$
• B. $13\pi m$
• C. $4\pi m$
• D. $6\pi m$

Answer 1

The correct option is A $\pi m$

$\theta =\frac{l}{r}as{30}^o=\frac{\pi }{6}l=r\theta =6\times \frac{\pi }{6}=\pi meters$
