The figure shows a diagonal symmetric arrangement of capacitors and a battery. If the potential of $C$is zero, then (All the capacitors are initially uncharged)

Two capacitors of $2\mathrm{\mu F} \& 3\mathrm{\mu F}$ are charged to $150 \mathrm{volt} \& 120 \mathrm{volt}$ respectively. The plates of a capacitor are connected as shown in the$\mathrm{fig}. \mathrm{A}$ discharged capacitor of capacity $1.5\mathrm{\mu F}$ falls to the free ends of the wire and connected through the free ends of the wire, Then :

In the adjoining diagram all the capacitors are initially uncharged, they are connected with a battery as a shown in figure. Then

In the circuit shown in the figure, each capacitor has a capacitance $C$. The emf of the cell is $E$ and circuit already in steady-state. If the switch $S$ is closed.

Two similar condensers are connected in parallel and are charged to a potential $V$. Now, these are separated out and are connected in series. Then, 

We have a combination as shown in the following figure. Choose the correct options.
