Given radius of earth \'R\' and length of a day \'T\' the height of a geostationary satellite is [G-Gravitational Constant, M-Mass of Earth]

A geo-stationary satellite is orbiting the earth at a height of 6 R above the surface of earth, R being the radius of earth. The time period of another satellite at a height of 2.5 R from the surface of earth is

A satellite is launched into a circular orbit of radius \' R\' around earth while a second satellite is launched into an orbit of radius 1.02 R. The percentage difference in the time periods of the two satellites is

Where can a geostationary satellite be installed?

Two satellites of earth S₁ and S₂ are moving in the same orbit. The mass of S₁is four times the mass of S₂. Which one of the following statements is true?

If the gravitational force between two objects were proportional to 1/R (and not as 1/R²) where R is separation between them, then a particle in circular orbit under such a force would have its orbital speed v proportional to

A satellite moves around the earth in a circular orbit of radius r with speed v. If the mass of the satellite is M, its total energy is

A satellite with kinetic energy E_k is revolving round the earth in a circular orbit. How much more kinetic energy should be given to it so that it may just escape into outerspace

Potential energy of a satellite having mass \'m\' and rotating at a height of 6.4 × 10⁶ m from the earth surface is

When a satellite going round the earth in a circular orbit of radius r and speed v loses some of its energy, then r and v change as
