Gravitation question

2020 · 9 Jan · Shift 1 · Q60

JEE MainPhysicsGravitationMCQ+4 / −1
A body A of mass m is moving in a circular orbit of radius R about a planet. Another body B of mass m2{m \over 2}2m​ collides with A with a velocity which is half (v→2)\left( {{{\overrightarrow v } \over 2}} \right)(2v​) the instantaneous velocity v→{\overrightarrow v }v of A. The collision is completely inelastic. Then, the combined body :
  1. A
    starts moving in an elliptical orbit around the planet.
  2. B
    Falls vertically downwards towards the planet
  3. C
    Escapes from the Planet's Gravitational field.
  4. D
    continues to move in a circular orbit
