What is the ratio of angular speed of hour hand and minute hand of a clock?

Answer»

Solution :ANGULAR SPEED of hour hand :
`omega_(1)=(2pi)/(12xx3600)" rad/s"`
For minute hand angular speed :
`omega_(2)=(2pi)/(3600)" rad/s"`
`THEREFORE (omega_(1))/(omega_(2))=(1)/(12)`
`therefore omega_(1):omega_(2)=1:12`
