An artificial satellite is revolving around the earth in a circular orbit of radius r. If the time period of revolution of the satellite is T, show that `T^2 prop r^3`.

Two small artificial satellite are revolving around the earth in two circular orbits of radii r and (r+Deltar) . If their time periods of revolution are T and T+Delta T , then (Deltar lt lt r, DeltaT lt lt T)

An artificial satellite of mass m is moving round the earth in an orbit of radius 2R. How much work is to be done to transfer the satellite to an orbit of radius 4R ? How will the potential energy of the satellite change ? (R=Radius of earth)

An aritificial satellite of mass m is moving round the earth, in an orbit of radius 2R. How much work is to be done to transfer the satellite to an orbit of radius 4R? How will the potential energy of the satellite change? (R = Radius of earth).

An artificial satellite revolves around the earth in a circular orbit and is at a height of 300 km above the surface of the earth. Find the orbital speed and the time period of the satellite. The radius of the earth=6400 km, g=980 cm*s^(-2) .

A geostationary satellite orbits around the earth surface in a circular orbit of radius 36,000 km. then, he time period of a spy satellite orbiting seventeen hundred kilometers above the earth's surface (R_e= 6400 km) will approximately be

A person inside an artificial satellite revolving around the earth feels weightless- true or false ?
