Statement-1: A satellite is moving in a circular orbit of the earth. If the gravitational pull suddenly disappears. Then it moves with the same speed tangential to the orginal orbit. Statement-2: the orbital speed of a satellite increases with the increase in radius of the orbit.

A satellite of mass m is in an elliptical orbit around the earth of mass M(M gt gt m) the speed of the satellite at its nearest point ot the earth (perigee) is sqrt((6GM)/(5R)) where R= its closest distance to the earth it is desired to transfer this satellite into a circular orbit around the earth of radius equal its largest distance from the earth. Find the increase in its speed to be imparted at the apogee (farthest point on the elliptical orbit).

Consider two satellites A and B of equal mass m, moving in the same circular orbit of radius r around the earth E but in opposite sense of rotation and therefore on a collision course (see figure) (i). In terms of G,M_(e) m and r find the total mechanical energy E_(A)+E_(B) of the two satellite plus earth system before collision (ii).
