The numerical value of the angular veloc...

The numerical value of the angular velocity of rotation of the earth should be ________ `rad s^(-1)` in order to make the effective acceleration due to gravity equal to zero.

Text Solution

Verified by Experts

The correct Answer is:
`1.23xx10^(-1)`
`g'=g-Rw^2`
Here g'=0
`therefore w=sqrt(g/R)=1.23xx10^(-3)` rad/s
