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

Let dielectric constant of material used be K.

+ + =

⇒K=12
