How would the force change if the distance between the objects were halved to 1/2r? 3. How would the force change if one object’s mass increased 3 times and the other increased 2 times? 4. How would the force change if one object’s mass increased 3 times and the other increased 2 times while the distance doubled to 2r? r = d (radius = distance) Solve the following problems using the equation F = G m1m2 r2 1. Calculate the force between two objects that have masses of 70 kilograms and 2,000 kilograms separated by a distance of 1 meter.</p><p>8 24 2. The distance between Earth and its moon is 4 X10 meters. Earth’s mass is m = 6X10 kilograms and the 22 mass of the moon is 7X10 kilograms. What is the force between Earth and the moon?</p>
