QNEET-2018-Ph-876: NEET 2018 Physics - Class 11 NEET-2018-Ph-876 Solution: If the mass of the Sun were ten times smaller and the universal …
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. Time period of a simple pendulum on the Earth would decrease. g on the Earth will not change.
Multiple Choice 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.
Step-by-Step Verified Solution
If universal gravitational constant becomes
ten times, then G' = 10 G
Acceleration due to gravity, g = G M R 2
So,
acceleration due to gravity increases, hence �g� on
the Earth will not change is not correct.
