If the electric field at point P is zero, what is the ratio $\frac{r_1}{r_2}$?

(Image description: A diagram shows two positive charges, $4q$ on the left and $q$ on the right, separated by a distance. A point P is located between them. The distance from $4q$ to P is labeled $r_1$, and the distance from P to $q$ is labeled $r_2$.)
