An artificial satellite circulating the earth is at a height `3400km` from the surface of the earth, if the radius of the earth is `6400km` and `g=9.8m/s^2`. calculate the orbital velocity of the satellite.

Two identical satellites are orbitting in circular orbits around the earth at heights R and 3R respectively from the surface of the earth. The radius of the earth is R. Define orbital velocity.

Calculate the electrical capacitance of earth. The radius of earth is 6400 km.

Two identical satellites are orbitting in circular orbits around the earth at heights R and 3R respectively from the surface of the earth. The radius of the earth is R. How do you compare the periods of revolution of these two satellites?

A geostationary satellite orbits the earth at a height of nearly 36,000km from the surface of the earth. What is the potentional due to earth's gravity at the site of this sattelite? (Take the potential energy at infinity to be zero). Mass of the earth=6×10^24kg ., radius of earth=6,400km .

Earth satellites are object which revolve around the earth. consider a satellite at a height 'h' from the surface of the earth. give an equation for its orbital velocity.
