Two satellites are at different heights from the surface of earth. Which would have greater velocity?

The communication satellites are parked at a height of (from surface of earth)

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)

The orbit velocity of a satellite at a height R above the surface of Earth is v . The escape velocity from the location is

If height of a satellite from the surface of earth is increased , then its

When the height of a satellite increases from the surface of the earth.

A geostationary satellite is nearly at a height of h = 6 R from the surface of the earth where R is the radius of the earth. Calculate the area on the surface of the earth in which the communication can be made using this satellite.

Two satellites 'A' and 'B' of masses ten and twenty metric tons revolve around the Earth at two different height h_(1) and h_(2) from the surface of the Earth. If earth's gravitational pull on these two satellites at these heights is equal, then find the ratio of their distances from the centre of the Earth . (Radius of the Earth = 6400 km)

The critical velocity of a satellite at height h from the surface of the earth is 5 km/s. The same for a satellite around another planet of double the radius and 4 times the mass of the earth and double the height will be

A satellite is revolving around earth in a circular orbit at a height (R )/(2) from the surface of earth. Which of the following are correct statements about it (M = mass of earth, R = radius of earth, m = mass of satellite) ?
