Question

Angular velocity of minute hand of a clock is

• A. $\frac{\pi }{30}rad{s}^{-1}$
• B. $\pi rad{s}^{-1}$
• C. $2\pi rad{s}^{-1}$
• D. $\frac{\pi }{1800}rad{s}^{-1}$

Answer 1

Answer: (D)

Minute hand of a clock rotates through an angle of 2$\pi$ in 60 min ie, 3600 s.
Angular velocity
$\omega =\frac{2\pi }{3600}=\frac{\pi }{1800}rad{s}^{-1}$
