If the net electric field at point $P$ along $Y$ axis is zero, then the ratio of $\frac{q _{2}}{q _{3}}$ is $\frac{8}{5 x}$ , where $x =$ _____.

Answer:

5.00

Solution:

$\frac{Kq _{2}}{20} cos β = \frac{Kq _{3}}{25} cos θ \frac{Kq _{2}}{20} \frac{4}{20} = \frac{Kq _{3}}{25} \frac{4}{25} \frac{q _{2}}{q _{3}} = \frac{20}{25} \frac{20}{25} = \frac{8}{5 x} \Rightarrow x = \frac{8 \times 25 25}{5 \times 20 20} x = 5$
