help with gravitational force
1. what happens to the gravitational force between two objects if the distance between them is increased 4 times?
a. increased 4 times
b. increased 16 times
c. reduced 4 times
d. reduced 16 times
I know it has to be decreased so I think the answer is c ???
2. assuming the distance between the objects were the same, which set of objects would have the greatest gravitational attraction?
a. object A with a mass of 3 kilograms and object B with a mass of 2 kilograms
b. object A with a mass of 3 kilograms and object b with a mass of 3 kilograms
c. object A with a mass of 2 kilograms and object b with a mass of 2 kilograms
d. all sets would have equal gravitational attraction
I think D is the answer
