A satellite is revolving in circular orbit of radius r around the eart

1.	A satellite is revolving in circular orbit of radius r around the earth of mass M. Time of revolution of satellite is
Answer» `Tprop(r^(5))/(GM)` `T propsqrt((r^(3))/(GM))` `T prop sqrt((r)/((GM^(2))/(3)))` `T prop sqrt((r^(3))/((GM)/(4)))` SOLUTION :The TIME PERIOD of revolution of satellite is given by `rArr T=2pisqrt((r^(3))/(GM))rArr T=prop sqrt((r^(3))/(GM))`.
