Some equipotential surfaces are shown in figure given below. The magnitude of electric field will be
Open in App
Solution
Since the equipotential planes are equally spaced, the electric field will be uniform.
The direction of →E will be perpendicular to the equipotential surfaces, and it will flow from high potential to low potential as shown in the figure.
From relation,
ΔV=Ed
Where, d = Perpendicular distance between two equipotential surfaces
