A satellite of mass m is orbiting close to the surface of the earth (Radius R = 6400 km) has a K.E. K. The corresponding K.E. of satellite to escape from the earth’s gravitational field is

The time period T of the moon of planet Mars(Mm) is related to its orbital radius R as (G = Gravitational constant)

A geostationary satellite is orbiting the earth at a height of 5 R above that of 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 earth is ............ hr

The figure shows elliptical orbit of a planet m about the sun s. the shaded area SCD is twice the shaded area SAB. If t₁ is the time for the planet to move from C and D and t₂ is the time to move from A to B then

The period of a satellite in a circular orbit of radius R is T. the period of another satellite in a circular orbit of radius 4R is

If the earth is at one- fourth of its present distance from the sun the duration of year will be

The orbital speed of jupiter is

Kepler’s second law regarding constancy of aerial velocity of a planet is consequence of the law of conservation of

The largest and shortest distance of the earth from the sun are r₁ and r₂ its distance from the sun when it is at the perpendicular to the major axis of the orbit drawn from the sun
