A parallel-plate capacitor has plate area `A`, the distance between its two plates `x` and `y` is `d` and a dielectric slab of dielectric constant `epsilon_(r)` is filled between the regions. It is connected to a cell of emf `E`. If the dielectric slab is removed, then

A parallel plate capacitor has a capacity 80xx10^(-6)F , when air is present between its plates. The space between the plates is 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 passing through the wire is
