Physics · Electrostatic Potential
हिन्दीAn equipotential surface is a surface with a constant value of potential at all points. Which of the following statements is correct regarding equipotential surfaces?
Correct answer · Option 2
Electric field is always normal to the equipotential surface at every point / प्रत्येक बिंदु पर विद्युत क्षेत्र हमेशा समविभव पृष्ठ के लंबवत होता है
Explanation
The electric field must be normal to the equipotential surface at every point, otherwise there would be a non-zero component of electric field along the surface, requiring work to move a charge.
