Two insulated charged spheres of radii $20\,cm$ and $25\,cm$ respectively and having an equal charge $Q$ are connected by a copper wire, then they are separated
ABoth the spheres will have the same charge $Q$
BCharge on the $20\;cm$ sphere will be greater than that on the $25\;cm$ sphere
CCharge on the $25\;cm$ sphere will be greater than that on the $20\;cm$ sphere
DCharge on each of the sphere will be $2Q$

CCharge on the $25\;cm$ sphere will be greater than that on the $20\;cm$ sphere
c (c)After the connection of wire ${V_1} = {V_2}$
$\frac{{{Q_1}}}{{25}} = \frac{{{Q_2}}}{{20}}$ $==>$ $\frac{{{Q_1}}}{{{Q_2}}} = \frac{{25}}{{20}}$ $ = = > $ ${Q_1} > {Q_2}$

In the circuit shown, the switch is shifted from position $1 \rightarrow 2$ at $t = 0$. The switch was initially in position $1$ since a long time. The graph between charge on capacitor $C$ and time $'t'$ is
Two parallel plate capacitor with different plate seperation but the same capacitance are connected in series to a battery. Both capacitors are filled with air. The quantity that is $NOT$ the same for both the capacitors when they are fully charged is
A capacitor of capacitance $C$ is charged to a potential difference $V$ from a cell and then disconnected from it. A charge $+Q$ is now given to its positive plate. The potential difference across the capacitor is now $Q$
The capacitance $(C)$ for an isolated conducting sphere of radius $(a)$ is given by $4\pi \varepsilon_0a$. If the sphere is enclosed with an earthed concentric sphere. The ratio of the radii of the spheres $\frac{n}{{(n - 1)}}$ being then the capacitance of such a sphere will be increased by a factor
The plates of a parallel plate capacitor are charged up to $100\, volt$. A $2\, mm$ thick plate is inserted between the plates, then to maintain the same potential difference, the distance between the capacitor plates is increased by $1.6\, mm$. The dielectric constant of the plate is
A capacitor of capacity $'C'$ is connected to a cell of $'V'\, volt$. Now a dielectric slab of dielectric constant ${ \in _r}$ is inserted in it keeping cell connected then
