Problem

A parallel-plate capacitor is connected to a

100\,\text{V}

battery and acquires a charge of

200\,\mu\text{C}

. While it remains connected to the battery, a dielectric slab of dielectric constant

4

completely fills the gap between the plates. The additional charge that flows from the battery to the capacitor is a)

400\,\mu\text{C}

600\,\mu\text{C}

800\,\mu\text{C}

200\,\mu\text{C}
