PhysicsElectrostatic Potential and CapacitanceMHT CET 2025

A parallel plate capacitor has plate area 50 cm and plate separation 3 mm. The space between the plates is filled with a dielectric medium of thickness 1 mm and dielectric constant 4. The capacitance becomes ( = permittivity of free space)

Answer: (B)

Solution

For a capacitor partly filled with a dielectric slab of thickness and dielectric constant : . Here , m, m, . The effective separation is \frac{t}{K}$ = (3 - 1
