The mass of object 1 was 10 kg. The mass of object 2 was 500 kg. The distance between the two objects was 10 m. The student calculated the gravitational force to be 3.34 x 10-9. Which of the following statements best describes the student’s calculations?
A. The calculations were correct, because multiplying the two masses (10 kg x 500 kg), then dividing by the distance squared (102), then multiplying by G (6.67 x 10-11 N•m2/kg2), gives 3.34 x 10-9.
B. The calculations were correct, because dividing the two masses (10 kg / 500 kg), then multiplying by the distance squared (102), then multiplying by G (6.67 x 10-11 N•m2/kg2), gives 3.34 x 10-9.
C. The calculations were incorrect, because multiplying the two masses (10 kg x 500 kg), then dividing by the distance squared (102), then multiplying by G (6.67 x 10-11 N•m2/kg2), gives 3.34 x 10-10.
D. The calculations were incorrect, because dividing the two masses (10 kg / 500 kg), then multiplying by the distance squared (102), then multiplying by G (6.67 x 10-11 N•m2/kg2), gives 1.15 x 10-9.

The coulomb's law explains which of the following? select all the force between two charged objects is inversely proportional to the charge on each object. the force between two charged objects is directly proportional to the charge on each object. the force between two charged objects is directly proportional to the distance separating them. the force between two charged objects is inversely proportional to the square of the distance separat coulomb's law is similar to newton's 2nd law. if the force between two objects is f and the charge on both objects is doubled, the new force between the would now be 2f. if the force between two objects is 2f and the distance separating them is doubled, the new force between the objects would now o the be zf.
