Calculate the angular speed of the hour ...

Calculate the angular speed of the hour hand of a clock .

A

`1/30`

B

`1/60`

C

`1/120`

D

`1/720`

Text Solution

Verified by Experts

The correct Answer is:
C
According to question, Net displacement of hour hand of a `theta 2pi=360^`circ
Time required for this displacement,
`t=12xx3600 s`
So, angular speed = `theta/t =360/12xx3600=1/120` degree/s
