A positive point charge \[\mathbf{(+q)}\] is kept in the vicinity of an uncharged conducting plate. Sketch electric field lines originating from the point charge on to the surface of the plate.             

Answer:

                Starting from the charge \[+q,\] the lines of force will terminate at the metal plate, inducing negative charge on it. At all positions, the lines of force will be perpendicular to the metal surface, as shown in Fig.
