The electric field $\vec E$ between two points is constant in both magnitude and direction. Consider a path of length d at an angle $\theta = 60^o$ with respect to field lines shown in figure. The potential difference between points $1$ and $2$ is
$\frac {E}{d\,cos\,60^o}$
$Ed\,cos\,60^o$
$\frac {Ed}{cos\,60^o}$
$\frac {E}{d}\,cos\,60^o$
In a certain charge distribution, all points having zero potential can be joined by a circle $S$. Points inside $S$ have positive potential and points outside $S$ have negative potential. A positive charge, which is free to move, is placed inside $S$
In a hollow spherical shell potential $(V)$ changes with respect to distance $(r)$ from centre
A solid conducting sphere, having a charge $Q$, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be $V$. If the shell is now given a charge of $-4\, Q$, the new potential difference between the same two surface is......$V$
If eight identical drops are joined to form a bigger drop, the potential on bigger as compared to that on smaller drop will be
Can the potential function have a maximum or minimum in free space ? Explain.
