The ratio of angular speeds of minute hand and hour hand of a watch is

A

`1:12`

B

`6:1`

C

`12:1`

D

`1:6`

Text Solution

Verified by Experts

The correct Answer is:
C
`omega_("min")=(2pi)/(60)"rad"//"min" and omega_(hr)=(2pi)/(12xx60)"rad"//"min"`
`(omega_("min"))/(omega_(h))=(2pi//60)/(2pi//12xx60)=(12)/(1)`
