QJEEM21Phd68a: JEE Main 2021 Physics - Class 12 JEEM21Phd68a Solution: In a parallel plate capacitor set up, the plate area of…

In a parallel plate capacitor set up, the plate area of capacitor is 2 m2 and the plates are separated by 1 m. If the space between the plates are filled with a dielectric material of thickness 0.5 m and area 2 m2 (see fig.) the capacitance of the set-up will be __________εo. (Dielectric constant of the material = 3.2) (Round off to the Nearest Integer)

Step-by-Step Verified Solution

C1=Kε0Ad/2;C2=ε0Ad/2

1C=1C1+1C2=d2Kε0A+d2ε0A

1C=d2ε0A(K+1K)

C=2ε0AKd(K+1)=2×2×3.21×4.2ε0=3.04ε0
