Question

1. 1. Which is true? The gravitational force between two particles:

a. can be shielded by the presence of an intervening mass.

b. is inversely proportional to the distance between the particles.

c. obeys the law of superposition.

d. is independent of the distance between the particles.

Answer 1

C. Obeys the law of superposition.

The gravitational force is inversely proportional to the square of the distance. It is not independent of it. Also, you can't shield the force by adding a mass. In fact, you increase it, which is what superposition tells us.
