A particle is situated at a height 3 R from the earth surface . The velocity with which it should be projected vertically upward so that it does not return to earth is

For two saatellitw at distance R and 7R above the earth's surface, the ratio of their

A body attains a height equal to the radius of the earth when projected from earth's surface the velocity of body with which it was projected is

Two artificial satellites A and B are at a distance r_(A) and r_(B) above the earth's surface. If the radius of earth is R, then the ratio of their speed will be :-
