Ration of angular velocity of hour hand ...

Ration of angular velocity of hour hand of a clock to self rotation of the earth is

A

`omega _(2) =(omega_(1))/(2)`

B

`omega_(1)=(omega_(1))/(2) `

C

`omega _(2) = (omega _(1))/(16)`

D

`omega_(1)=(omega_(2))/(16)`

Text Solution

Verified by Experts

The correct Answer is:
B
For the earth , `T_(1) =24` h and for the hour hand `T_(2) = 12 h and omega=(2pi)/(T)`
` therefore omega_(1) = (2pi)/(24) and omega_(2) = (2pi)/(12) therefore omega_(1) =(omega_(2))/(2)`
