Question 21 • Physics in the Universe

How does the electrical force relate to the charge of an object?

Answer
A
It is directly proportional to the square of the charge.
B
It is inversely proportional to the square of the charge.
C
It is directly proportional to the charge.
D
It is inversely proportional to the charge.

Explanation

By Coulomb’s law, the electrical force between two objects is proportional to the product of their charges. If the other object’s charge and the distance stay the same, doubling one object’s charge doubles the force. So the force is directly proportional to the charge, as choice A states.
