Question
A parallel plate capacitor with air between the plates has a capacitance of 9 pF. The separation between its plates is ′d′. The space between the plates is now filled with two dielectrics. One of the dielectrics has dielectric constant k2 = 3 and thickness 
while the other one has dielectric constant k2 = 6 and thickness 
. Capacitance of the capacitor is now
while the other one has dielectric constant k2 = 6 and thickness . Capacitance of the capacitor is nowOptions
A.1.8 pF
B.45 pF
C.40.5 pF
D.20.25 pF
