Question

beyond the atmosphere the gravitational pull of earth becomes very less if we go out of earth atmosphere we are atracteed towards earth centre but we do not reenter into earth atmosphere because gravitational pull is very less but then how does moon is atracted toward earth ?

Answer 1

The Earth and the Moon both attract each other with the same amount of force. Moon does not move towards Earth, rather it revolves around it. This force of gravitation between the two provides necessary centripetal force for the orbital motion of the Moon. The same amount of force is acting on both, but the mass of Earth is large in comparison with Moon. Due to this, the lighter moon revolves around the heavier Earth and not vice-versa.
