Question

how would the value of g and G affected if mass of earth becomes four times​

Answer 1

Answer:

Gravity is in g is equal to earth masses/earth radius^2. ... This means that 4 Earth would have a radius that is cube root 4 bigger than Earth. So due to the mass, the gravity increases by a factor of 4.
