A satellite is orbiting around the earth in a circular orbit and in this orbit magnitude of its acceleration is a_1 . Now a rocket is fired in the direction of motion of satellite from the satellite due to which its speed instantaneously becomes half of initial, just after the rocket is fired acceleration of satellite has magnitude a_2 . Then the ratio (a_(1))/(a_(2)) is (Assume there is no external force other than the gravitational force of earth before and after the firing of rocket from the satellite)

A small satellite of mass m is revolving around earth in a circular orbit of radius r_(0) with speed v_(0) . At certain point of its orbit, the direction of motion of satellite is suddenly changed by angle theta = cos^(-1) (3/5) by turning its velocity vector , such that speed remains constant. The satellite consequently goes to elliptical orbit around earth. the ratio of speed at perigee to speed at apogee is

Assertion (A) : The time period of revolution of a satellite around a planet is directly proportional to the radius of the orbit of the satellite. Reason (R) : Artifical satellite do not follow Kepler's laws of planatory motion.
