A satellite is going around the earth in an elliptical orbit and has maximum and minimum distance from the centre of earth equal to 10r and r respectively. It was planned to fire on board rocket so as to increase the energy of the satellite by maximum amount. Assume that the rocket is fired for a small time (almost instantaneous) and gives an impulse J to the satellite in forward direction. Take J to be small compared to overall momentum of the satellite.

1.	A satellite is going around the earth in an elliptical orbit and has maximum and minimum distance from the centre of earth equal to 10r and r respectively. It was planned to fire on board rocket so as to increase the energy of the satellite by maximum amount. Assume that the rocket is fired for a small time (almost instantaneous) and gives an impulse J to the satellite in forward direction. Take J to be small compared to overall momentum of the satellite.
Answer» Correct Answer - (b) J=0.01 m sqrt((GM)/r)`

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
