Which has less angular speed, hour hand of clock or the angular speed of earth on its own axis?

Answer»

Solution :Angular SPEED of earth is LESS
For earth angular speed
`omega_(e)=(2pi)/(24xx3600)" rad/s"`
`omega_(h)=(2pi)/(12xx3600)" rad/s"`
`THEREFORE (omega_(e))/(omega_(h))=(1)/(2)`
`therefore 2omega_(e)=omega_(h)`
`therefore omega_(e)ltomega_(h)`
