If the net electric field at point P along Y axis is zero, then the ratio of |q_2/q_3| is 8/(5 √ x), where x= ____.

If the net electric field at point P along Y axis is zero, then the ratio of $\displaystyle \left|\frac{q_2}{q_3}\right|$ is $\displaystyle \frac{8}{5 \sqrt{x}}$, where $\displaystyle x=$ $\displaystyle \_\_\_\_$.
