A satellite which is geostationary in a ...

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

`48sqrt2` hours

C

24 hours

D

`24 sqrt2` hours

Text Solution

Verified by Experts

The correct Answer is:
B
`Tpropr^(3/2)`
`(T_1)/(T_2)=(r/(2r))^(3/2)rArrT_2=(2)^(3/2)xx24`
`=48sqrt` hours
