A mass m is raised from a distance 2 R from the surface of the earth to 3R. Work done to do so against gravity will-

A body of mass m is raised to aheight h from the surface of the earth where the acceleration due to gravity is g. Prove that the loss in eight due to variation in g is approximately 2 mgh // R, where R is the radius of the earth.

A satellite A of mass m is at a distance of r from the surface of the earth. Another satellite B of mass 2m is at a distance of 2r from the earth's centre. Their time periods are in the ratio of

The earth has mass M and radius R .An object of mass m is dropped from a distance of 3R , from the centre of the earth.The object strikes the surface of the earth with a speed , v=sqrt(kgR) ,where g is acceleration due to gravity or the surface of the earth.The value of k

A mass m is taken to a height R from the surface of the earth and then is given a vertical velocity upsilon . Find the minimum value of upsilon , so that mass never returns to the surface of the earth. (Radius of earth is R and mass of the earth m ).

A mass m is taken to a height R from the surface of the earth and then is given a vertical velocity upsilon . Find the minimum value of upsilon , so that mass never returns to the surface of the earth. (Radius of earth is R and mass of the earth m ).

A particle of mass 'm' is raised from the surface of earth to a height h = 2R. Find work done by some external agent in the process. Here, R is the radius of earth and g the acceleration due to gravity on earth's surface.
