The additional kinetic energy to be provided to a satellite of mass m revolving around a planet of mass M, to transfer it from a circular orbit of radius R1 to another of radius R2 (R2 > R1) is

A satellite of mass m is orbiting the earth (of radius R) at a height h from its surface. The total energy of the satellite in terms of go, the value of acceleration due to gravity at the earth’s surface, is

Two satellites of earth S1 and S2 are moving in the same orbit. The mass of S1 is four times the mass of S2. Which one of the following statements is true

Two satellites A and B go around a planet in circular orbits having radii 4R and R, respectively. If the speed of satellite A is 3u, then speed of satellite B is

A remote-sensing satellite of earth revolves in a circular orbit at a height of 0.25×10^6 m above the surface of earth. If earth’s radius is 6.38×10^6 m and g=9.8ms^-2, then the orbital speed of the satellite is

If ve, and vo, represent the escape velocity and orbital velocity of a satellite corresponding to a circular orbit of radius R, then

A geostationary satellite is orbiting the earth at a height of 5R above that surface of the earth, R being the radius of the earth. The time period of another satellite in hours at a height of 2R from the surface of the earth is
