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. Raindrops will fall faster.
  2. Walking on the ground would become more difficult.
  3. Time period of a simple pendulum on the Earth would decrease.
  4. 'g' on the Earth will not change.

Correct answer · Option 2

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.
