Two point charges are fixed on the $y$ axis: a negative point charge $q_{1}=-25 \mu \mathrm{C}$ at $y_{1}=+0.22 \mathrm{m}$ and a positive point charge $q_{2}$ at $y_{2}=+0.34 \mathrm{m}$ . A third point charge $q=+8.4 \mu \mathrm{C}$ is fixed at the origin. The net electrostatic force exerted on the charge $q$ by the other two charges has a magnitude of 27 $\mathrm{N}$ and points in the $+y$ direction. Detcrmine the magnitude of $q_{2}$ .
