1.

A satellite is revolving in circular orbit of radius `r` around the earth of mass M. Time of revolution of satellite isA. `Tprop(r^(5))/(GM)`B. `T propsqrt((r^(3))/(GM))`C. `T prop sqrt((r)/((GM^(2))/(3)))`D. `T prop sqrt((r^(3))/((GM)/(4)))`

Answer» Correct Answer - B
The time period of revolution of satellite is given by
`rArr T=2pisqrt((r^(3))/(GM))rArr T=prop sqrt((r^(3))/(GM))`.
