Question

Angular speed of hour hand of a clock in degree per second is (A) (1/30) (B) (1/60) (C) (1/120) (D) (1/720)

Time taken by the hour hand to complete one rotation of 360° is 12 hours i.e.43200 seconds Thus its angular velocity w =(360/43200) We get w=(1/120) degree per second

$\frac{1}{30}$

$\frac{1}{60}$

$\frac{1}{120}$

$\frac{1}{720}$

Time taken by the hour hand to complete one rotation of $36 0^{\circ}$ is $12$ hours i.e. $43200$ seconds
Thus its angular velocity $w = \frac{360}{43200}$
We get $w = \frac{1}{120}$ degree per second
