Two charged conducting spheres of radii $a$ and $b$ are connected to each other by a conducting wire. The ratio of charges of the two spheres respectively is:
$\sqrt{\mathrm{ab}}$
$a b$
$\frac{a}{b}$
$\frac{\mathrm{b}}{\mathrm{a}}$
Equal charges are given to two spheres of different radii. The potential will
Draw a graph showing variation of potential with $r$ distance for a uniformly charged spherical shell.
If the potential of the inner shell is $10\,V$ and that of the outer shell is $5\,V$, then potential at the centre will be....$V$
Write an equation for potential at a point in a uniformly charged spherical shell.
Two charged spheres of radii $10\, cm$ and $15\, cm$ are connected by a thin wire. No current will flow, if they have
