The angular momentum `(L)` of the earth revolving round the sun uis proportional to `r^(n)`, where `r` is the orbital radius of the earth. The value of `n` is (assume the orbit to be circular)

The angular momentum J of the electron in a hydrogen atom is proportional to n^(th) power of r (radius of the orbit) where n is :-

The earth revolves round the sun in an elliptical orbit. Its speed

When the earth revolves round the sun in an elliptical orbit, its kinetic energy is

Angular momentum of a satellite revolving round the earth in a circular orbit at a height R above the surface is L . Here R is radius of the earth. The magnitude of angular momentum of another satellite of the same mass revolving very close to the surface of the earth is
