MCQ
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? 
  • A
    Raindrops will fall faster.
  • B
    Walking on the ground would become more difficult.
  • ✓
      $‘g’ $ on the Earth will not change.
  • D
    Time period of a simple pendulum on the Earth would decrease.
✓

Answer

Correct option: C.
  $‘g’ $ on the Earth will not change.
c
If universal Gravitational constant becomes ten times, then $G' = 10\ G.$
So, acceleration due to gravity increases.
