Question

Match List I with List II :

Column I	Column II
(A) Kinetic energy of planet	(I) $- \frac{GM m}{a}$
(B) Gravitation Potential energy of sun-planet system	(II) $\frac{GM m}{2 a}$
(C) Total mechanical energy of planet	(III) $\frac{G m}{r}$
(D) Escape energy at the surface of planet for unit mass object	(IV) $- \frac{GM m}{2 a}$

(Where a = radius of planet orbit, r = radius of planet, M = mass of Sun, m = mass of planet)
