The ratio of angular speed of the minute hand of the clock to that of its hour hand is?
Correct answer: D. 12:1
- A. 3600:1
- B. 60:1
- C. 24:1
- D. 12:1
Explanation
d) 12:1: This option is correct. The ratio of angular speed of the minute hand of the clock to that of its hour hand is 12:1. This means that the minute hand rotates 12 times faster than the hour hand in one hour.

About Angular Velocity
Angular velocity describes how quickly angular displacement changes with time, with ω = Δθ/Δt and units of radians per second. Questions relate angular and linear motion through v = rω, use the direction given by the right hand rule, and distinguish angular velocity from angular acceleration and ordinary frequency.
