Question

Hi I don’t understand question and can really use some help! :D

Answer 1

Given

Mass of one of the object is doubled and the distance between the object is doubled.

To find

What happens to the gravitational force

Step-by-step explanation

The gravitational force is directly proportional to the masses and inversely proportional to the distance between them

Keeping all other parameters constant,

`F\propto(m)/(d^2)`

So when the mass doubles and the distance doubles we have,

`\begin{gathered} F^(\prime)\propto(2m)/((2d)^2) \\ \Rightarrow F\propto(m)/(2d)=(F)/(2) \end{gathered}`

Conclusion

A. The gravitational force becomes half as great.
