Write an equation for potential due to volume charge distribution.
Draw a graph showing variation of potential with $r$ distance for a uniformly charged spherical shell.
Variation in electric potential is maximum if one goes
As shown in the figure, charges $ + q$ and $ - q$ are placed at the vertices $B$ and $C$ of an isosceles triangle. The potential at the vertex $A$ is
Consider two conducting spheres of radii ${{\rm{R}}_1}$ and ${{\rm{R}}_2}$ with $\left( {{{\rm{R}}_1} > {{\rm{R}}_2}} \right)$. If the two are at the same potential, the larger sphere has more charge than the smaller sphere. State whether the charge density of the smaller sphere is more or less than that of the larger one.
The radius of a soap bubble whose potential is $16\,V$ is doubled. The new potential of the bubble will be.....$V$
