Problem

A satellite is moving in a low nearly circular orbit around the earth. Its radius is roughly equal to that of the earth's radius

R_e

. By firing rockets attached to it, its speed is instantaneously increased in the direction of its motion so that it become

\sqrt{\frac{3}{2}}

times larger. Due to this the farthest distance from the centre of the earth that the satellite reaches is

R

. Value of

R

is : (1)

4R_e

(2)

2.5R_e

(3)

3R_e

(4)

2R_e
