1.	A point mass is orbiting a significant mass M lying at the focus of the elliptical orbit having major and minor axes given by 2a and 2b respectively. Let r be the distance between the mass M and the end point of major axis. Velocity of the particle is given as
Answer» `(AB)/(r ) SQRT((GM)/(a^3))` `(ab)/(r ) sqrt((GM)/(b^3))` `(ab)/(2R ) sqrt((GM)/(r^3))` `(2ab)/(r ) sqrt((GM)/((a+b)/(2))^(3))` ANSWER :A
