Physics - Capacitor Question with Solution | TestHub

A capacitor of $10\mu \mathrm{F}$ capacitance whose plates are separated by $10\mathrm{mm}$ through air and each plate has area $4{\mathrm{cm}}^2$ is now filled equally with two dielectric media of ${\mathrm{K}}_1=2,{\mathrm{K}}_2=3$ respectively as shown in figure. If new force between the plates is $8\mathrm{N}$. The supply voltage is _________ $\times 10^{-4}\mathrm{V}$.
