Solving a problem in physics section 68 point 81 electr

81. A point charge of 2 ∙ 10−6 C is located near a charged infinitely extended plane. Under the influence of the field, the charge moves along the field line to a point located at a distance of 2 cm from the plane. In this case, the work is 0.5 J. Find the surface charge density of the plane.
