The surface charge density of a thick metal plate is sigma the electric field near the surface is |
|
Answer» Answer: Explanation: According to gauss theorem E= q/ε Here q is the charge of the conductor now, σ=q/ds q=σds HENCE, E.dscosθ = σds/ε As the unit VECTOR is NORMAL to to the surface in the upward DIRECTION. Hence the angle between the electric field and area vector is 0 E.ds = σds/ε E=σ/ε |
