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.
