The angular velocity of the earth's rotation about its axis is `omega`. An object weighed by a spring balance gives the same reading at the equator as at height `h` above the poles. The value of `h` will be

A

`(R^(2) omega^(2))/(2 g)`

B

`(R^(2) omega^(2))/(g)`

C

`(R^(2) omega^(2))/(4g)`

D

`(R^(2) omega^(2))/(8g)`
