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?

Raindrops will fall faster Walking on the ground would become more difficult ‘g’ on the Earth will not change Time period of a simple pendulum on the Earth would decrease

‘g’ on the Earth will not change

If Universal Gravitational constant becomes ten times, then G' = 10 G. So, acceleration due to gravity increases. i.e. (3) is wrong option.
