A body revolved around the sun 27 times faster then the earth what is the ratio of their radii

A body revolved around the sun 27 times faster then the Earth what is the ratio of their radii

Two satellites orbiting around the earth have their critical speeds in the ratio 4 : 5. What is the ratio of their orbital radii ?

A satellite is going in a circular orbit of radius 4 xx 10^5 km around the earth has a certain speed. (b) What will be the ratio of the weight of a body on the surface of Mars to tyhe weight of the same body on the surface of the earth? The masses of earth and Mars are in the ratio 10:1 and their radii are in the ratio 2:1

When the earth revolves around the sun, the work done by the gravitational force of the sun is zero.

An asteroid of mass 2 xx 10^(-4) M_e , where M_e is the mass of the earth, revolves in a circular orbit around the sun at a distance that is twice earth's distance from the sun. Find the ratio of the kinetic energy of the asteroid to that of earth
