Question

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?, Time period of a simple pendulum on the Earth would decrease, Walking on the ground would become more difficult, Raindrops will fall faster, g on the Earth will not change

MARKS App · Accepted Answer

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.
