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.

  1. Solution:
    Normal component of Electric field intensity due to a thin infinite plane sheet of

    (b) To show that the tangential component of electrostatic field is continuous from one side of a charged surface to another, we use the fact that work done by electrostatic field on a closed loop is zero.
