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 isA. 48 hB. `24sqrt2h`C. `48sqrt2h`D. 24 h |
Answer» Correct Answer - c `(T_(2))/(T_(1))=((r_(2))/(r_(1)))^(3//2)=((2r_(1))/(r_(1)))^(3//2)` `T_(2)=T_(1)xx2sqrt2` `=24xxsqrt2=48sqrt2h`. |
