Expert Answer:
Hi dear,
The electric field in relation to potential is Ex = dV/dx. Along an equipotential surface there is no change in V with position x parallel to the surface so dV/dx = 0, making Ex = 0. There is no component of field parallel to the surface, so the field is normal to the surface.
Hope this helps.
