Question 1182904
<br>
Increasing the mass of each body by 60% multiplies the masses by a factor of 1.6.<br>
Halving the distance between the bodies multiplies the distance by 1/2.<br>
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<br>
{{{((1.6)(1.6))/(.5)^2 = 10.24}}}<br>
Multiplying the force by a factor of 10.24 means the force is increased by 924%.<br>
ANSWER: 924%<br>
