why most electrostatic field be normal to the surface at every point of a charged conduction?

Expert Answer:

One of the most important properties of an equipotential surface is:

The electric field is always at right angles to the equipotential surface.


Since all points of an equipotential surface are at same potential, no work is done in moving a test charge between any two points on the equipotential surface.
