Question 16 • TX-Physics B

Both the electrical force and the gravitational force between two objects share which relationship?

Answer
A
They are directly proportional to mass.
B
They are inversely proportional to the square of the distance.
C
They are inversely proportional to charge.
D
They are directly proportional to the square of the distance.

Explanation

Both forces follow an inverse-square relationship with separation distance. The gravitational force is proportional to 1/r², and Coulomb’s electrical force is also proportional to 1/r², where r is the distance between the objects. Therefore, both become weaker as the distance increases, matching “inversely proportional to the square of the distance.”
