Question

A parallel plate capacitor is of area 6 cm² and a separation 3 mm. The gap is filled with three dielectric materials of equal thickness (see figure) with dielectric constants K₁ = 10, K₂ = 12 and K₃ = 14. The dielectric constant of a material which when fully inserted in above capacitor, gives same capacitance would be:
(A) 4 (B) 14
(C) 12 (D) 36

Answer 1

I hope it is helpful for u!!

Answer 2

treat them as 3 capacitor in paralle
