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.
View Answer & Solution

Correct answer · Option B

Walking on the ground would become more difficult.

Explanation

Acceleration due to gravity \( g = \frac{GM}{R^2} \). If \( G \) becomes 10 times, \( g \) on Earth will increase 10 times. Therefore, statement 4 ('g' on the Earth will not change) is INCORRECT.
