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?
  1. Raindrops will fall faster
  2. Time period of a simple pendulum on the Earth would decrease
  3. 'g' on the Earth will not change
  4. Walking on the ground would become more difficult

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

g=GMR2,
g is depends in 'G', hence 'g' will change.
Hence raindrops will fall faster and walking on ground will more difficult.
Time period 1g, hence 'T' decreases.
