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 ?

Options

A. Raindrops will fall faster
B. Walking on the ground would become more difficult
C. Time period of a simple pendulum on the Earth would decrease
D. ' g' on the Earth will not change

Answer

D

Explanation

As `m_s.=(m_s)/10` and `G.=10G`
`g_E=(G.M_E)/(R^2)=(10GM_E)/(R^2)=10g`
`therefore` Raindrops will fall faster, Walking on the ground would become more difficult, Time period of a simple pendulum on the earth decreases.
