A satellite which is geostationary in a particular orbit is taken to another orbit. Its distance from the centre of earth in new orbit is 2 times that of the earlier orbit. The time period in the second orbit is

(a) 4.8 hours                         (b) $48\sqrt{2}$ hours

(c) 24 hours                           (d) $24\sqrt{2}$ hours

(b)     $T\propto {r}^{3/2}$. If r becomes double then time period will becomes ${\left(2\right)}^{3}{2}}$ times.
So new time period will be  i.e. $T=48\sqrt{2}$
