Question 16: NCERT Solutions for 12th Class Physics: Chapter 2-Electrostatic Potential and Capacitance
Show that the normal component of electrostatic field has a discontinuity from one side of a charged surface to another given by
where n is a unit vector normal eo to the surface at a point and o is the surface charge density at that point. (The direction of n is from side 1 to side 2). Hence show that just
outside a conductor, the electric field is
(b) Show that the tangential component of electrostatic field is continuous from one side of a charged surface to another.
