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
