if two spheres are in contact , then these two spheres will become single object .

Hence there is no gravitational force

i just want to know why a ball falls on earth when left from a height becuse the gravitional forces of both of them is equal and opposite hence the ball must tend to be at rest in the air .I have already consulted few lecturers but their answer were complicated and tough to understand so i want to get a simpler answer so that i acn understand it in a proper way

Sir,The gravitational due to a uniform disc at a point in its axis is 2GMr/R²((1/r)-(1/√(r²+R²))).Andthe potential at a point in the axis is -2GM/R²(√(R²+r²)-r) where R-radius and r-distance in the axis. Also,We know that on differentiating gravitational potential we get the gravitational field at that point.But that is not the case for disc.On integrating the potential we are not getting the value of the field.Why is it so? Please help
