Four metallic plates each of area $A$ and separated from one another by a distance $d$ are arranged as shown in the figure. What is the capacitance between $X$ and $Y ?$

A capacitor of capacitance $4\mu F$ is charged to a potential of $100 \mathrm{V}.$ It is then disconnected from the battery and connected in parallel with another capacitor $C_2.$ If their common potential is $40$ volts, then the value of $C_2$ is

An uncharged parallel plate capacitor filled with an oil is connected in parallel with an identical but air filled capacitor charged to a potential $V_1$. If the common potential is $V_2$, the dielectric constant of the oil is

In the circuit diagram shown in the adjoining figure, the resultant capacitance between $P$ and $Q$ is

In the given circuit, one of the $3\mu \mathrm{F}$ capacitors has $600\mu \mathrm{J}$ of energy. Then the potential difference across $2\mu \mathrm{F}$ capacitor is
