A parallel plate capacitor with air between the plates has a capacitance of 9 pF. The seperation between its plates is d. The space between the plates is now filled with two dielectrics. One of the dielectrics has dielectric constant k₁=3 and thickness d/3 while the other one has dielectric constant k₂=6 and thickness 2d/3. Capacitance of the capacitor is now
Options
(a) 20.25 pF
(b) 1.8 pF
(c) 45 pF
