An artificial satellite is at a height of 36,500 km above earth's surface. What is the work done by earth's gravitational force in keeping it in its orbit ?

An artificial satellite is orbiting at a height of 1800 km from the surface of earth. What is speed of the satellite ? (R = 6300 km)

An artificial satellite is orbiting at a height of 1800 km from the earth's surface. The earth's radius is 6300 km and g=10m/s^(2) on its surface. What is the radial acceleration of the satellite?

A geostationary satellite is at a height h above the surface of earth. If earth radius is R -

A geostationary satellite orbits the earth at a height of nearly 36,000 km from the surface of the earth. What is the potential due to earth's gravity at the site of the satellite ? Mass of the earth= 6xx10^(24) kg and radius =6400 km.

A remote sensing satellite of the earth revolves in a circular orbit at a height of 250 km above the earth's surface. What is the (i) orbital speed and (ii) period of revolution of the satellite ? Radius of the earth, R=6.38xx10^(6) m, and acceleration due to gravity on the surface of the earth, g=9.8 ms^(-2) .

An artificial satellite is revolving in a circular orbit at height of 1200 km above the surface of the earth. If the radius of the earth is 6400 km and mass is 6xx10^(24) kg , the orbital velocity is

Statement I: Consider a satellite moving in an elliptical orbit around the earth. As the satellite moves, the work done by the gravitational force of the earth on the satellite for any small part of the orbit is zero. Statement II: K_(E) of the satellite in the above described case is not constant as it moves around the earth.

How much time would a satellite in an orbit at a height of 35780 km above the earth's surface take to complete one revolution around the earth , if the mass of the earth were four times its original mass ?

A body is being raised to a height h from the surface of earth. What is the sign of work done by (a) applied force (b) gravitational force ?
