Let omega be the angular velocity of the earth's rotation about its axis. An object weighted by a spring balance gives the same reading at the equator as at a height h above the poles (h lt lt R). The value of h is

Let omega be the angular velocity of the earth's rotation about its ax

1.	Let omega be the angular velocity of the earth's rotation about its axis. An object weighted by a spring balance gives the same reading at the equator as at a height h above the poles (h lt lt R). The value of h is
Answer» `(OMEGA^(2) R^(2))/(g)` `(omega^(2) R^(2))/(2g)` `(2omega^(2) R^(2))/(g)` `(sqrt(RG))/(omega)` ANSWER :B
