Q. Two parallel plate capacitors $C_1$ and $C_2$ each having capacitance of $10\, \mu F$ are individually charged by a $100\, V D . C$. source. Capacitor $C_1$ is kept connected to the source and a dielectric slab is inserted between it plates. Capacitor $C_2$ is disconnected from the source and then a dielectric slab is inserted in it. Afterwards the capacitor $C_1$ is also disconnected from the source and the two capacitors are finally connected in parallel combination. The common potential of the combination will be ___$V$ (Assuming Dielectric constant $=10$ )
