CBSE · Class 12 · Physics · Electrostatic Potential and CapacitanceThe angle between electric field lines and equipotential surface is always:
Step-by-Step Solution
Since work done along equipotential surface is zero ($W = q E dr \cos\theta = 0$), $\cos\theta = 0 \implies \theta = 90^\circ$. Electric field is always perpendicular to equipotential surfaces.
