Question

What is the shape of the equipotential surfaces for a single point charge (+q)?

पर्याय

• Concentric spheres centred on the charge

• Co-axial cylinders

• Parallel planes perpendicular to the field

• Complex closed curves bulged near the charge

Answer 1

For a single point charge (+q), the equipotential surfaces are concentric spheres centred on the charge. The field lines are radially outward and perpendicular to these spheres, satisfying the property that \[\vec{E}\] is always normal to the equipotential surface.
