A paralel-plate capacitor is charged by connecting it to a battery. The battery is then disconnected and the distance between the plates is doubled. This doubles

A 5 $\mu$F capacitor is charged to a p.d. of 10 V. If it is further charged, so that its p.d. increases to 20 V, the electric energy stored in it increases by

A 5 $\mu$F capacitor is connected in series with a 10 $\mu$F capacitor and the combination is connected across a 9 V battery. The potential differences across the capacitors are in the ratio

The effective capacitance of a capacitor is reduced when capacitors are connected in :

Three capacitors of capacitances 2 μF, 3 μF and 6 μF are connected in series. The equivalent capacitance of the combination is

Two capacitors each of capacitance 4 $\mu$F are connected in series, and a third capacitor of capacitance 4 $\mu$F is connected in parallel with the combination. Then, the equivalent capacitance of the arrangement is
