Gravitational Field Due To Spheres

Two bodies of masses m and M are placed at distance d apart. The gravitational potential (V) at the position where the gravitational field due to them is zero V is

Find the gravitational potential at a point where the gravitational field intensity is zero due to two particles of masses m_(1)=1kg and m_(2)=4kg separated through a distance l=3m ?

There are three identical point mass bodies each of mass m locted at the vertices of an equilateral triangle with side r . They are experting gravitational force of attraction on each other, which can be given by Newton's law of gravitaiton. Each mass body produces its gravitational field in the surrounding region. the magnitude of gravitational field at a point due to a point mass body is the measure of gravitaitonal intensity at that point. The gravitational potential at a point in a gravitational field is the amount of workdone in bringing a unit mass body infinity to the given point without acceleration. Answer the following questions : The magnitude of the gravitational force on one body due to other two bodies is

If gravitational potential is V = xy^(2) , find the gravitational field at (2,1)

Assertion : If gravitational potential at some point is zero, then gravitational field strength at that point will also be zero. Reason : Except at infinity gravitational potential due to a system of point masses at some finite distance can't be zero.
