$\frac{\pi}{6}$ radian per hr

Work Step by Step

Step 1: The formula to be used here is $w=\frac{\theta}{t}$ Step 2: Since the hour hand of the clock makes one complete rotation in $12$ hours, $\theta=2\pi$ radians in $t=12$ hours. Step 3: Substituting these values in the formula, $w=\frac{2\pi}{12}=\frac{\pi}{6}$ radian per hr
