A very large conducting plate lying in the xy plane carries a charge per unit area of +5.0 nC/m2. A second such plate located above the first plate at z = z0 and oriented parallel to the xy plane carries a charge per unit area of -5.0 nC/m2. Find the electric field for (a) z < 0, (b) 0 < z < z0, and (c) z > z0.
Determine the electric field intensity created by a line of charge parallel to the z axis at x=6, y=8 at the point (3,4,5), density of charge= 1nano Coulomb/meter.
If a line of charge with uniform density ρl extends between z=-L/2 and z=L/2 along the z-axis, obtain an expression for the electric field intensity at any point P(r, ϕ ,0) on the x-y plane.
Investigate the case when L becomes infinite.
