Question : 8 of 160

Marks: +1, -0

A parallel plate capacitor has a capacity 80×10−6F, 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 through the wire is

45.6×10−3C
25.3×10−3C
120×10−3C
125×10−3C
