Question

The angular speed of the minute hand of a clock in degrees per second is

• A. \( 0.01 \)
• B. \( 0.1 \)
• C. \( 1 \)
• D. \( 10 \)

Hint:

Minute hand covers \( 360^\circ \) in one hour; always convert time to seconds when asked per second.

Answer 1

The Correct Option is B

Step 1: Determine angular displacement of minute hand.
The minute hand completes one full revolution in \( 60 \) minutes, i.e. \( 360^\circ \) in \( 3600 \) seconds.
Step 2: Calculate angular speed.
\[ \omega = \frac{\text{Angular displacement}}{\text{Time}} = \frac{360^\circ}{3600\,\text{s}} = 0.1^\circ/\text{s} \]
Step 3: Conclusion.
The angular speed of the minute hand is \( 0.1^\circ/\text{s} \).
