If the potential is constant on a surface,then any electric field present can only be perpendicular to that surface.

This is a consequence of the fact that electric field lines are always perpendicular to the equipotential surfaces. If the potential is constant on a surface, then all the points on the surface have the same potential and therefore lie on the same equipotential surface. Any electric field present must be perpendicular to this surface in order to maintain the constant potential.
