easy

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

Both the spheres will have the same charge $Q$

Charge on the $20\;cm$ sphere will be greater than that on the $25\;cm$ sphere

Charge on the $25\;cm$ sphere will be greater than that on the $20\;cm$ sphere

Charge on each of the sphere will be $2Q$

Solution

(c)After the connection of wire ${V_1} = {V_2}$
$\frac{{{Q_1}}}{{25}} = \frac{{{Q_2}}}{{20}}$ $==>$ $\frac{{{Q_1}}}{{{Q_2}}} = \frac{{25}}{{20}}$ $ = = > $ ${Q_1} > {Q_2}$
