Two identical satellites are moving around the Earth in circular orbits at heights 3R and R respectively where R is the radius of the Earth. The ratio of their kinetic energies is x. Find x.

Two identical satellites A and B are circulating round the earth at the height of R and 2 R respectively, (where R is radius of the earth). The ratio of kinetic energy of A to that of B is

Two satellites A and B of the same mass revolve around the earth in circular orbits. They are at heights of R and 3R respectively from the surface of the earth (R=radius of the earth). Find the ratio of their kinetic energies and potential energies.

Two identical satellites are orbiting are orbiting at distances R and 7R from the surface of the earth, R being the radius of the earth. The ratio of their
