Question : 106

Total: 160

A parallel plate capacitor has a capacity 80 × 10−6 F when air is present between its plates. The space between the plates is tilled with a dielectric slab of dielectric constant 20. The capacitor is now connected to a battery of 30 V by wires. The dielectric slab is then removed. Then the charge passing through the wire is

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