Two oppositely rotating satellities of same are launched in the same orbit round the earth. The collide idealistically. What is the ratio of gravitational potential energy before and after collistion?

Two satellites P and Q are in the same circular orbit round the earth. The mass of Pis greater than that Q. It follows that

Two satellites of same mass are launched in the same orbit round the earth so as to rotate opposite to each other. They soon collide inelastically and stick together as wreckage. Obtain the total energy of the system before and just after the collision. Describe the subsequent motion of the wreckage.

Two earth-satellite are revolving in the same circular orbit round the centre of the earth. They must have the same

Two earth-satellite are revolving in the same circular orbit round the centre of the earth. They must have the same

Two identical satellite are kept in the same orbit around the earth to move in opposite directions. If they collide and stick together after some time

Two satellites of same mass are launched in circular orbits at height of 2R and 3R respectively. The ration of kinetic energies is

Two satellite of same mass are launched in the same orbit of radius r around the earth so as to rotate opposite to each other. If they collide inelastically and stick together as wreckage, the total energy of the system just after collision is
