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
- ATime period of a simple pendulum on the Earth would decrease
- BWalking on the ground would become more difficult
- CRaindrops will fall faster
- Dg on the Earth will not change
Correct answer
D. g on the Earth will not change
Step-by-step solution
m s ′ = m s 10 a n d G ′ = 10 G g E = G ′ M E R 2 = 10 G M E R 2 = 10 g ∴ Raindrops will fall faster, Walking on the ground would become more difficult, Time period of a simple pendulum on the earth would decrease.
