B$10$
b (b) Net capacitance $ = \frac{1}{{\left( {\frac{1}{2} + \frac{1}{3} + \frac{1}{6}} \right)}} = 1\,\mu F$
Total charge $ = CV = 1\,\mu F \times 10\,V = 10\,\mu C$
Total charge on every capacitor in series system is same. So charge on $3\, µF$ is $10\,µC$.

A network of four capacitors of capacity equal to $C_1 = C, C_2 = 2C, C_3 = 3C$ and $C_4 = 4C$ are conducted in a battery as shown in the figure. The ratio of the charges on $C_2$ and $C_4$ is
A paralle plate capacitor is made up of stair like structure with a palte area $A$ of each stair and that is connected with a wire of length $b$, as shown in the figure. The capacitance of the arrangement is $\frac{ x }{15} \frac{\varepsilon_{0} A }{ b }$. The value of $x$ is ............
Two condensers, one of capacity $C$ and other of capacity $C/2$ are connected to a $V-$ volt battery, as shown in the figure. The work done in charging fully both the condensers is
A parallel plate capacitor is charged to a certain potential and the charging battery is then disconnected. Now, if the plates of the capacitor are moved apart then:
A particle of charge $q$ and mass $m$ is subjected to an electric field $E = E _{0}\left(1- ax ^{2}\right)$ in the $x-$direction, where $a$ and $E _{0}$ are constants. Initially the particle was at rest at $x=0 .$ Other than the initial position the kinetic energy of the particle becomes zero when the distance of the particle from the origin is
In the circuit, shown in fig. $‘K’$ is open. The charge on capacitor $C$ in steady state is $q_1$. Now key is closed and at steady state, the charge on $C$ is $q_2$. The ratio of charges $\left( {\frac{{{q_1}}}{{{q_2}}}} \right)$ is
The charges on two plates of a $10\,\mu f$ capacitor are $5\,\mu C$ and $15\,\mu C$ then the potential difference across the capacitor plates is........$V$
