    (Given, \[{{\mathbf{V}}_{\mathbf{1}}}\mathbf{<}{{\mathbf{V}}_{\mathbf{2}}}\mathbf{<}{{\mathbf{V}}_{\mathbf{3}}}\mathbf{<}{{\mathbf{V}}_{\mathbf{4}}}\]) The four equipotential surfaces are shown in the figure. Draw the corresponding electric field lines for the given pattern of the equipotential surfaces. Also, state the region in which the electric field intensity is more,


    Since, we know that, the electric field lines are perpendicular to equipotential surfaces and \[E=-dV/dr\] Negative sign implies that electric potential drops in the direction of electric field. The region C will have higher electric field intensity
