Question

1. How does the force of gravitation between two objects change
when the distance between them is reduced to half ?​

Answer 1

Answer:

Increases by 4 times.

Explanation: Because,

F=Gm1m2/r²

So, F is directly proportional to 1/r²

So, when r is reduced to half,

F'=Gm1m2/(r/2)²

F'=4Gm1m2/r²

F'=4F

Answer 2

Answer:

increase by 4 times, the explanation is given in the above attachment
