Question

Angular velocity of minute hand of a clock is:

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

Answer 1

Answer: (D)

Minute hand of a clock rotates through an angle of $2\pi$ in $60$ minutes i.e. $3600sec$
$\therefore$ Angular velocity
$\omega =\frac{2\pi }{3600}=\frac{\pi }{1800}rad/s$
