ANSWER

why the electric field lines are perpendicular to the equipotential surface?

Posted by Praveen Kumar 7 years, 11 months ago

CBSE > Class 12 > Physics

1 answers

Aparna Sharma 7 years, 11 months ago

If electric field lines is not perpendicular to the surface then it will have one tangential component due to which work has to be done against this electric field, but from the definition of equipotential surface the work done on the surface must be zero. Hence, electric field needs to be perpendicular to the surface.
