A small satellite is revolving near earth's surface. Its orbital velocity will be nearly [CPMT 1987; Orissa JEE 2002; JIPMER 2001, 02]

A geostationary satellite [CPMT 1990]

Two satellites A and B go round a planet P in circular orbits having radii 4R and R respectively. If the speed of the satellite A is 3V, the speed of the satellite B will be. [MNR 1991; AIIMS 1995; UPSEAT 2000]

The relay satellite transmits the T.V. programme continuously from one part of the world to another because its [MNR 1984, 93]

If a satellite is orbiting the earth very close to its surface, then the orbital velocity mainly depends on [NCERT 1982]

The period of a satellite in a circular orbit around a planet is independent of [NCERT 1974; AIEEE 2004]

If \[{{v}_{e}}\] and \[{{v}_{o}}\] represent the escape velocity and orbital velocity of a satellite corresponding to a circular orbit of radius R, then [CPMT 1982; MP PMT 1997; KCET (Engg./Med.) 1999; AIIMS 2002]
