7)In calculating the force of gravity between two objects, if the mass of one object increased by 4 and the other by 2, how many times would the force of gravity increase?

I don't really understand but I got 6 times

8)In calculating the force of gravity between two objects, if the distance between the objects increased 4 times, the force of gravity will.

Decrease by 4 times

1. 7) Look at Newton's universal law of gravity.

F = G M m /R^2

I suggest you memorize it. The gravitational attraction force is proportional to the product, not the sum, of the masses. Try again.

8) Note the inverse square dependence upon distance in the law of gravity, which I just provided. Try again.

If you are not willing to make a serious effort to learn your assignments, you will not obtain much more help here.
