A body A of mass m is moving in a circular orbit of radius R about a planet. Another body B of mass m/2 collides with A with a velocity which is half ((v)/2) the instantaneous velocity v of A. The collision is completely inelastic. Then, the combined body:

(A) starts moving in an elliptical orbit around the planet.

(B) Falls vertically downwards towards the planet

(C) Escapes from the Planet's Gravitational field.

(D) continues to move in a circular orbit

A body A of mass m is moving in a circular orbit of radius R about a planet. Another body B of mass

{m \over 2}

collides with A with a velocity which is half

\left( {{{\overrightarrow v } \over 2}} \right)

the instantaneous velocity

{\overrightarrow v }

of A. The collision is completely inelastic. Then, the combined body :
