An infinite and grounded conducting plane sits on the xy plane at z = 0. Above the plane, positive charges q₁ and q2 are placed on the z axis at positions z = a and z = b respectively, with a ≤ b. Using the method of images, find the induced charge density on the conducting plane at radius P from the origin.Gauss's law Formulated by Karl Friedrich Gauss (1777-1855), a German Mathematician. Provide a means in determining the electric field or electric field intensity as produced by charge (point or distributed). Since Coulombs Law is already popular in point charges, Gauss's Law is more useful in distributed charges specially if it is symmetrically distributed in a closed system, such as charges in long wire or in a relatively infinite plane.
