Physics - Capacitor Question with Solution | TestHub

For changing the capacitance of a given paralle plate capacitor, a dielectric material of dielectric constant$K$is used, which has the same area as the plates of the capacitor. The thickness of the dielectric slab is$\frac{3}{4}d$, where$d$is the separation between the plates of parallel plate capacitor. The new capacitance$C^{\text{'}}$in terms of original capacitance$C_0$is given by the following relation :
