Question

the gravitational force between two object is f how will the force change when the distance between them is reduced to half and the mass of one object becomes four times​

Answer 1

Answer:

the force increases by 16 times

Explanation:

f=Gmm'

r²

m--4m; r--r/2

f'=G(4m)m' = 4×Gmm'

(r/2)² r²/4

f'=(4×4)f

f'=16f

therefore the force increases by 16 times
