Q25. A capacitor of $10 \mu \mathrm {~F}$ capacitance whose plates are separated by 10 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 N . The supply voltage is $\_\_\_\_$ $\times 10 ^ { - 4 } \mathrm {~V}$. [Figure] (we modified language of question to make it correct)
