If the massn 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. `'g'` on the earth will not change
B. rain drops will fall faster
C. time period of a simple pendulam on the earth would decreases
D. walking on the ground would becomes more difficult

Answer

A

Explanation

`m_(s)=(m_(s))/10` and `G'=10G`
`g_(E)=(G'M_(E))/(R^(2))=(10GM_(E))/(R^(2))=10g`
`:.` Raindrop will fall faster, Walking on the around would becomes more difficult, time period of a simple pendulam on the earth would decreases.
