Gravitation question

2016 · 10 Apr · Shift 1 · Q58

JEE MainPhysicsGravitationMultiple correct+4 / −1
An astronaut of mass m is working on a satellite orbiting the earth at a distance h from the earth’s surface. The radius of the earth is R, while its mass is M. The gravitational pull FG on the astronaut is :
  1. A
    Zero since astronaut feels weightless
  2. B
    0 < FG < GMmR2{{GMm} \over {{R^2}}}R2GMm​
  3. C
    GMm(R+h)2{{GMm} \over {{{\left( {R + h} \right)}^2}}}(R+h)2GMm​< FG <GMmR2{{GMm} \over {{R^2}}}R2GMm​
  4. D
    FG = GMm(R+h)2{{GMm} \over {{{\left( {R + h} \right)}^2}}}(R+h)2GMm​
