A parallel plate capacitor has a capacity 80×10−6 F when air is present between the plates. The volume between the plates is then completely filled with a dielectric slab of dielectric constant 20. The capacitor is now connected to a battery of 30V by wires. The dielectric slab is then removed. Then, the charge that passes now thorugh the wire is

45.6×10−3 C
25.3×10−3 C
120×10−3 C
12×10−3 C
