$6 \mu \mathrm{F}$ and $6 \mu \mathrm{F}$ are in series
$\therefore$ Voltage ascross $4 \mu \mathrm{F}=6 \mathrm{V}$
$\therefore Q=6 \times 4 \times 10^{-6}$
$=24 \times 10^{-6} \mathrm{C}$

The diagram shows three infinitely long uniform line charges placed on the $X, Y $ and $Z$ axis. The work done in moving a unit positive charge from $(1, 1, 1) $ to $(0, 1, 1) $ is equal to
The capacitance of a parallel plate capacitor is $12\,\mu \,F$. If the distance between the plates is doubled and area is halved, then new capacitance will be.........$\mu \,F$
In the figure shown below, the charge on the left plate of the $10\, \mu F$ capacitor is $-30\,\mu C.$ The charge on the right place of the $6\,\mu F$ capacitor is.....$\mu C$
Charge $q_{2}$ is at the centre of a circular path with radius $r$. Work done in carrying charge $q_{1}$, once around this equipotential path, would be
An infinite number of charges each equal to $0.2\,\mu C$ are arranged in a line at distances $1\,m, 2\,m, 4\,m, 8\,m......$ from a fixed point. The potential at fixed point is ......$kV$
The respective radii of the two spheres of a spherical condenser are $12\;cm$ and $9\;cm$. The dielectric constant of the medium between them is $ 6$. The capacity of the condenser will be
Three long concentric conducting cylindrical shells have radii $R, 2R$ and $2\sqrt 2 $ $ R$ . Inner and outer shells are connected to each other. The capacitance across middle and inner shells per unit length is:
