Question 385: Gravitation

Question

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?

Accepted Answer

If universal gravitational constant becomes
ten times, then G' = 10 G
Acceleration due to gravity, g = $${{GM} \over {{R^2}}}$$
So,
acceleration due to gravity increases, hence Ã¢ÂÂgÃ¢ÂÂ on
the Earth will not change is not correct.

Answer

Answer

Walking on the ground would become more
difficult.

Answer
