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).

Assertion : For circular orbits, the law of periods is T^(2) prop r^(3) , where M is the mass of sun and r is the radius of orbit. Reason : The square of the period T of any planet about the sun is proportional to the cube of the semi-major axis a of the orbit.
