Which is greater , the angular velocity of the hour hand of a watch or angular velocity of earth around its own axis ?

Text Solution

Verified by Experts

`T_(h)` =Time period of hour hand of watch `T_(e)` =Time period of earth `T_(h)`= 12 hours `T_(e)` = 24 hour
Angular velocity `omega=(2pi)/(T) (omega_(h))/(omega_(e))=(T_(e))/(T_(h))=(24)/(12)=2 omega_(h) =2omega_(e)`
