An earth satellite is revolving in a circular orbit of radius a withh a velocity `v_(0)`. A gun in the satellite is directly aimed toward earth. A bullet is fired from the gun with muzzle velocity `(v_(0))/2`. Find the ratio of distance of farthest and closest approach of bullet from centre of earth. (Assume that mass of the satellite is very-very large with respect to the mass of the bullet)

An earth satellite is revolving in a circular orbit of radius a with velocity upsilon_(0) . A gun in the satellite is aimed directly towards the earth. A bullet is fired from the gun with muzzle velocity (upsilon_(0))/(2) . Neglecting resistance offered by cosmic dust and recoil of gun, calculate maximum and minimum distance of bullet from the center of earth during its subsequent motion.

An earth satellite is revolving in a circular orbit of radius a with velocity upsilon_(0) . A gun is the satellite and is aimed directly towards the earth. A bullet is fired from the gun with muzzle velocity (upsilon_(0))/(2) . Neglecting resistance offered by cossmic dust and recoil of gun, calculate maximum and minimum distance of bullet from the centre of earth during its subsequency motion.

A satellite is orbiting around the Earth in a circular orbit with velocity v. If m is the mass of the satellite, its total energy is ........ .

A satellite of the earth is revolving in circular orbit with a uniform velocity V . If the gravitational force suddenly disappers, the satellite will-

A satellite is revolving round the earth (mass M_(e) ) in a circular orbit of radius a with velocity V_(0) A particle of mass m is projected from the satellite in forward direction with relative velocity v[sqrt((5)/(4))-1]V_(0) . During subsequent motion of particle.
