In figure-6.105, particle A has a mass of `1.4` and particle B has a mass of `3.1 kg`. What is the gravitational field at point P ?

A particle of mass m has momentum p. What is its kinetic energy ?

Two particles P and Q are initially at rest and 1 m aparts. P has a mass of 1 kg and Q a mass of 3 kg . P and Q attract each other with a constant force. At what distance from P's original position do the particles collide?

The gravitational field in a certain region is given as vec(E) = (3N kg^(-1)) hat(i) + (5N kg^(-1)) hat(j) (a) What will be magnitude of gravitational force acting on a particle of mass 3 g which is placed at the origin ? (b) What will be gravitational potential at point (12m, 0) and (0, 6m) considering that potential at origin is zero ? (c ) A particle of mass 3 kg is moved from the origin to the point (9m, 4m). Calculate the change of gravitational potential energy. (d) If the above particle is moved from (5m, 0) to (0, 5m), then find the change in potential energy.

The gravitational force on a body of mass 1.5 kg situated at a point is 45 M . The gravitational field intensity at that point is .

Two particle of masses 4kg and 8kg are kept at x=-2m and x=4m respectivley. Then, the gravitational field intensity at the origin is
