A capacitor of capacitance 5$\mu$F is charged by a battery of emf 10V. At an instant of time, the potential difference across the capacitors is 4V and the time rate of change of potential difference across the capacitor is 0.6 V/s. Then the time rate at which energy is stored in the capacitor at the instant is

A parallel plate capacitor is charged by connecting a 2 Volt battery across it. It is then disconnected from the battery and a glass slab is introduced between plates. Which of the following pair of quantities decrease ?

Eight drops of mercury of equal radii combine to form a big drop. The capacitance of a bigger drop as compared to each smaller drop is
