The angular velocity of the hours hand of a 24 hr clock
The angular velocity of the hours hand of a 24 hr clock
1 Answer
Arun
Dear student
The hour hand completes 1 single round in 12 hours.
1 single round is equal to 2π radians.
Angular speed = Angular Displacement/Time Taken = 2π/12 hours
In this manner, you can get the answer in radians per hour or you can convert hours to seconds and get the answer in radians per second.
