Dear abhishek


artificial setelite revolves around the earth near to the earth . with a acceleration of GM/R2    


 Where R is radius of orbit if setelite rotation.


when mass is inside the setellite .two force act on it gravitational pull by earth and normal reaction


so


GMm/R2 -N =m(GM/R2)  according to newton law


so N=0


 so body is weightless in this case


 


but when a body is on the moon then here gravitational pull by moon on body can not be neglected as its mass of moon is large


so here wieght of the mass due to gravitational pull by moon


F= GMmm/Rm2
