Question

Show that the equipotential surfaces are closed together in the regions of strong field and far apart in the regions of weak field. Draw equipotential surface for an electric dipole.

Answer 1

Equipotential surfaces are closer togehter in the regions of strong feild and furthure apart in the regions of weak field.
$$ E= -\dfrac{dV}{dr} $$
E= negative potential gradient
For same change in dv, equipotential surfaces. $$ E= -\dfrac{dV}{dr} $$
where 'dr' represents the distance between
