Question 1182904: Newton's law of gravitation states that every body in the universe attracts every other body with a force F that varies directly as the product of their masses (m1 and m2) and inversely as the square of the distance d between them. If both masses are increased by 60% and the distance between them is halved, by what percent will the force of attraction increase? Round your answer to nearest integer

Newton's law of gravitation states that every body in the universe attracts every other body with a force F that varies directly as the product of their masses (m1 and m2) and inversely as the square of the distance d between them.
F = %28m1%2Am2%29%2Fd%5E2
If both masses are increased by 60% and the distance between them is halved, by what percent will the force of attraction increase? Round your answer to nearest integer
Let's assume original masses were 1 and the distance was 1 (F=1) then we can write it:
F = %281.6%2A1.6%29%2F.5%5E2
F = 2.56%2F.25
F = 10.24
which is
10.24*100 = 1024%

Increasing the mass of each body by 60% multiplies the masses by a factor of 1.6.

Halving the distance between the bodies multiplies the distance by 1/2.

The force varies jointly as the two masses and inversely as the square of the distance. So increasing the mass of each body by 60% and halving the distance changes the gravitational force by a factor of

%28%281.6%29%281.6%29%29%2F%28.5%29%5E2+=+10.24

Multiplying the force by a factor of 10.24 means the force is increased by 924%.

ANSWER: 924%
