The gravitational potential energy of an isolated system of three particles, each of mass m, placed at the corners of an equilateral triangle of side l is:
A satellite of mass m is orbiting the Earth (of radius R) at a height h from its surface. What is the total energy of the satellite in terms of g0? (g0 is the value of acceleration due to gravity at the Earth's surface)
A satellite of mass 1000 kg revolves in a circular orbit around the Earth with a constant speed of 100 m/s. The total mechanical energy of the satellite is:
A body of mass m is taken from the Earth's surface to a height equal to twice the radius (R) of the Earth. The change in potential energy of the body will be:
