Question

Which statement best explains the relationship between the electric force between two charged objects and the distance between them?

A. As the distance increases by a factor, the electric force increases by the square of that factor.

B. As the distance increases by a factor, the electric force increases by twice that factor.

C. As the distance increases by a factor, the electric force decreases by twice that factor.

D. As the distance increases by a factor, the electric force decreases by the same factor.

E. As the distance increases by a factor, the electric force decreases by the square of that factor.

Answer 1

Statement 'E' is the correct choice. As the distance increases by
a factor, the electric force decreases by the square of that factor.

Notice that this is EXACTLY the same as in the case of gravity.
