Draw the pattern of electric field lines when a point charge +q is kept near an uncharged conducting plate.

One side of conducting plate will have –ve charge induced at one surface of plate because of +ive charge q and the electric field lines will be perpendicular to the surface because the surface is equipotential and as the plate was uncharged at starting to maintain the neutrality of conducting plate +ive charge will be induced on the other side of plate.
