If we shift a body in equilibrium from A to C in a gravitational field via path AC or ABC,

In which condition a body lying in gravitational field is in stable equilibrium?

If a body of mass m is at a distance r in the gravitational field of a body of mass M , what will be the gravititional potential energy of the body ?

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 : Magnitude of gravitational field at the mid point D of arm BC of triangle ABC is

The velocity of a body falling freely under gravitational field varies as g^(p)h^(q) , where g is gravitational acceleration and h is height from which the body is released. p and q are given by

Assertion: The centre of gravity of a body coincides with its centre of mass only if the gravitational field does not vary form one part of the body to the other. Reason: Centre of gravity is independent of the gravitational field.

Answer the following questions : Work done in taking one body far away from the other two bodies is

Assertion : Gravitational potential is maximum at infinite. Reason : Gravitational potential is the amount of work done to shifting a unit mass from infinity to a given point in gravitational attraction force field.
