A conducting slab of copper PQRS is kept on the xy plane in a uniform magnetic field along x-axis as indicated in the figure. A steady current I flows through the cross section of the slab along the y-axis. The direction of the electric field inside the slab, arising due to the applied magnetic field is along the :-
