What is the change in potential energy (in calories) of a 10 kg mass after 41.8 m fall ?

If total energy of a satellite is negative, then orbit is:

Work required to move a 2 kg mass from surface of earth to height 4x is:

Change in gravitational potential energy from surface to height 3R is:

The ratio of the mass of two planets is 2 : 3 and ratio of their radii is 3 : 2. The ratio of accele
