1:
the gravitational force between two objects (mass1 = 10 kg, mass2 = 6 kg) is measured when the objects are 12 cm apart. if the distance between them is increased to 48 cm, how does the new gravitational attraction compare to the first one that was measured?

select one:
the gravitational force is 9 times stronger than before.
the new gravitational force is 16 times more.
the new gravitational force is 16 times smaller than the old one.
the new gravitational force is 6 times smaller than the original force.

2:
the gravitational force between two objects (mass1 = 5 kg, mass2 = 2 kg) is measured when the objects are 10 cm apart. if the 5 kg mass is replaced with a 20 kg mass and the 2 kg mass is replaced with a 6 kg mass, how does the new gravitational force attract compared to the first that was measured?

select one:
the new gravitational force is 12 times larger.
12 kg
the new gravitational force is 120 times greater.
it attracts less.

3:
the gravitational force between two objects (mass1 = 10 kg, mass2 = 6 kg) is measured when the objects are 12 cm apart. if the distance between them is increased to 36 cm, how does the new gravitational attraction compare to the first one that was measured?

select one:
the new gravitational force is 9 times smaller than the old one.
the gravitational force is 9 times stronger than before.
the new gravitational force is three times less than the original.
the new gravitational force is 6 times smaller than the original force.

4:
the gravitational force between two objects (mass1 = 5 kg, mass2 = 2 kg) is measured when the objects are 40 cm apart. if the 5 kg mass is replaced with a 10 kg mass and the 2 kg mass is replaced with a 8 kg mass, how does the new gravitational force attract compared to the first that was measured?

select one:
10 times more
