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.

C

$‘g’ $ on the Earth will not change.

D

Time period of a simple pendulum on the Earth would decrease.

(NEET-2018)

Solution

If universal Gravitational constant becomes ten times, then $G' = 10\ G.$
So, acceleration due to gravity increases.
