We know that N = mg , where N is normal reaction and mg is the force with which Earth is pulling a body . Now if i place another body ,lets say 10 ^12 kgs at a distance of 1 m from the body , will the larger body pull the smaller body horizontally towards itself , both these bodies are in contact with the surface of Earth , not joined to surface. will friction come into play in opposing the attraction towards each other ??
Now the problem i am facing is that when the larger body rests on the surface, it automatically becomes part of (earth+body) which is a composite system and 10^12 < < 10^24(mass of Earth ) so the smaller body won't experience any pull unless the mass becomes comparable to the order of Earth's mass and if we have a very dense body , 10^12 kg packed in a meter then it will pull the smaller body with a force of 6.7 m/s^2 which is comparable to 9.8 of Earth .
Also it must be that for the larger body to pull smaller one it shud have mass much greater than Earth to overcome Earth's gravity
