JEE MainPhysicsCapacitorMCQ+4 / −1
Co is the capacitance of a parallel plate capacitor with air as a medium between the plates (as shown in Fig. 1). If half space between the plates is filled with a dielectric of relative permittivity ε\varepsilonε r (as shown in Fig. 2), the new capacitance of the capacitor will be : JEE Main 2022 (Online) 30th June Morning Shift Physics - Capacitor Question 61 English
