Problem

A satellite can be in a geostationary orbit around the Earth at a distance rr from the centre. If the angular velocity of Earth about its axis doubles, a satellite can now be in a geostationary orbit around Earth if its distance from the centre is : (A) r2\frac{r}{2} (B) r22\frac{r}{2\sqrt{2}} (C) r(4)1/3\frac{r}{(4)^{1/3}} (D) r(2)1/3\frac{r}{(2)^{1/3}}
