Question 147: Gravitation

Question

The time period of a satellite revolving around earth in a given orbit is 7 hours. If the radius of orbit is increased to three times its previous value, then approximate new time period of the satellite will be

Accepted Answer

$$T_2^2 = {\left( {{{{R_2}} \over {{R_1}}}} ight)^3}T_1^2$$
$$ \Rightarrow {T_2} = {(3)^{3/2}} 	imes 7 \approx 5.2 	imes 7$$
$${T_2} \cong 36$$ hrs
