A solid sphere of radius R and mass density rho is surrounded by another outer sphere of density 2 rho . Let E_(P) is gravitational field at P and E_(Q) is at Q. If the ratio of E_(Q)//E_(P)=3k//4 . Find the value of k.

Calculate the minimum speed required by a rocket to pull out of the gravitational force of Mars. Given that the earth has a mass 9 times and radius twice of the planet Mars. Escape speed on the surface of earth is 11.2 km s^(-1) .

A point P lies on the axis of a fixed ring of mass M and radius a , at a distance a from its centre C . A small particle starts from P and reaches C under gravitational attraction only. Its speed at C will be.
