Example Question #3 : Electricity And Magnetism

If the distance between two charged particles is doubled, the strength of the electric force between them will __________.

Possible Answers:

be halved

remain unchanged

quadruple

double

be quartered

Correct answer:

be quartered

Explanation:

Coulomb's law gives the relationship between the force of an electric field and the distance between two charges:

The strength of the force will be inversely proportional to the square of the distance between the charges.

When the distance between the charges is doubled, the total force will be divided by four (quartered).
