A satellite which is geostationary in a particular orbit is taken to another orbit. Its distance from the center of earth in new orbit is two times of the earlier orbit. The time period in second orbit is` .........` hours.

Options

A. 4.8
B. `48sqrt(2)`
C. 24
D. `24sqrt(2)`

Answer

B

Explanation

`T prop r^(3/2)` if r becomes double then time period will become `(2)^(3/2)` times so new time period will be `24xx2sqrt(2)` hours , i.e ., `48sqrt(2)` hours.
