Question

In a uniform electric field, the equipotential surfaces take the shape of:

विकल्प

• Parallel planes perpendicular to the field

• Concentric spheres

• Co-axial cylinders

• Random closed curves

Answer 1

In a uniform electric field, the equipotential surfaces are parallel planes perpendicular to the field, and the field lines are parallel straight lines. Since \[\vec{E}\] must be normal to the equipotential surface, the planes must be oriented perpendicular to the uniform field direction.
