Two similar satellites `s_1` and `s_2` of same mass `m` possess around completely inelastic collision while orbiting earth in the same circular orbit in opposite direction then

A satellite of mass 5M orbits the earth in a circular orbit. At one point in its orbit, the satellite explodes into two pieces, one of mass M and the other of masses 4M . After the explosion the mass M ends up travelling in the same circular orbit, but in the opposite direction. After explosion the mass 4M is

Two artificial satellites of the same mass are moving around the earth in circular orbits of different radii. In comparision to the satellite with lesser orbital radius, the other satellite with higher orbital radius will have:

Two artificial satellites of the same mass are moving around the earth in circular orbits of different radii. In comparision to the satellite with lesser orbital radius, the other satellite with higher orbital radius will have:

Two artificial satellites of the same mass are moving around the earth in circular orbits of different radii. In comparision to the satellite with lesser orbital radius, the other satellite with higher orbital radius will have:

Assertion (A) : Two artificial satellites havirig different masses and revolving around the Earth in the same circular orbit have same speed. Reason (R) : The speed of a satellite is directly proportional to the radius of its orbit.
