Gravitation question

2018 · Q153

NEETPhysicsGravitationMCQ+4 / −1
If the mass of the Sun were ten times smaller and the universal gravitational constant were ten times larger in magnitude, which of the following is not correct?
  1. A
    Raindrops will fall faster.
  2. B
    Walking on the ground would become more difficult.
  3. C
    Time period of a simple pendulum on the Earth would decrease.
  4. D
    g on the Earth will not change.

Correct answer: D

If universal gravitational constant becomes ten times, then G' = 10 G

Acceleration due to gravity, g = GMR2{{GM} \over {{R^2}}}R2GM​

So, acceleration due to gravity increases, hence ‘g’ on the Earth will not change is not correct.
