Work done by gravitational force on an artificial satellite moving around the earth in circular orbit is zero.

Persons sitting in an artificial satellite orbiting around the earth have

Work done on an artificial satellite by gravity is zero while moving around the earth.

A satellite revolves around the earth in an elliptical orbit. Its speed is

When a satellite moves around the earth (consider elliptical orbits),

Define Earth's gravitational force

A satellite is moving in an orbit around the earth due to

The gravitational force on a body of mass 5 kg at the surface of the earth is 50 N. If earth is a perfect sphere, the gravitational force on a satellite of mass 200 kg in a circular orbit of radius same as diameter of the earth is

Consider a hypothetical planet which is very long and cylinderical. The density of the planet is rho , its radius is R . What is the possible orbital speed of the satellite in moving around the planet in circular orbit in a plane which is perpendicular to the axis of planet?

The maximum possible velocity of a satellite orbiting round the earth in a stable orbit is
