QJEEM21Ph3b8c: JEE Main 2021 Physics - Class 12 JEEM21Ph3b8c Solution: For changing the capacitance of a given parallel plate…

For changing the capacitance of a given parallel 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') in terms of original capacitance (C₀) is given by the following relation :
