Question

The gravitational force of two iron balls is 4 newton what will the gravitational force between them if the distance between them is reduced to half?​

Answer 1

Answer:

4times=16N

Explanation:

F=GMm/r²

F'=GMm/r²/4

=4GMm/r²

=4*4=16N

Answer 2

Dear Student,

◆ Answer -

16 N

● Explanation -

Let m1 and m2 be masses of two iron balls and r be the distance between them.

Gravitational force between these balls is -

F = Gm1m2/r²

4 = Gm1m2/r²

If this distance is reduced to half, r' = r/2

F' = Gm1m2/r'²

F' = Gm1m2/(r/2)²

F' = 4Gm1m2/r²

F' = 4 × 4

F' = 16 N

Hence, the gravitational force between two iron balls is 16 N.

Thanks dear. Hope this helps you..
