A parallel-plate capacitor of area a, plate separation d and capacitance C is filled with four dielectric materials having dielectric constants k1, k2, k3 and k4 as shown in the figure. If a single dielectric material is to be used to have the same capacitance C in this capacitor, then its dielectric constant k is given by
NEET 2016 Phase 2 Physics - Capacitor Question 32 English
A
k = k1 + k2 + k3 + 3k4
B
k = $${2 \over 3}$$ (k1 + k2 + k3) + 2k4
C
$${2 \over k}$$ = $${3 \over {{k_1} + {k_2} + {k_3}}} + {1 \over {{k_4}}}$$
D
$${1 \over k}$$ = $${1 \over {{k_1}}} + {1 \over {{k_2}}} + {1 \over {{k_3}}} + {3 \over {2{k_4}}}$$
