2 Answersevery object produces gravitation field and this gravitational field exert a force on another object and vice versa
Hi
It was observed that every object applies force on every other object. Then it was made a law, a gravitational law . Law is somehing which is always valid , for eg, newtons law are mere observations and u cannot prove them or contradict them.
Likewise, Gravitation is a universal phenomenon, that exist and is in the nature of each object that posseses mass. Cause of this force is the mass of the object , and no reason for why there is a force, its a universal fact.

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.

A car loaded with water having total mass 1000 kg moves on a straight horizontal Road starting from rest under the action of a force of 100 Newton. The water spills throw a small hole in the bottom at a rate of 0.1 KG per second the velocity of cart after 300 seconds is nearly.
