A parallel plate capacitor of capacitance 10muF is connected to a cell of emf 10 V and is fully charged. Now a dielectric slab (k = 3) of thickness equal to the gap between the plates is completely filled in the gap, keeping the cell connected. During the filling process, |

Answer» the increase in charge on the capacitor is `200 muC` . Initial charge (before filling the dielectric slab) is `10 xx 10 = 100` `muC`. Final charge (after filling the dielectric slab) is `10 xx 30 = 300 muC`. Increasing in charge is `20 muC`. |
