Problem

A charged particle enters a gravity-free space occupied by an electric field E\mathbf E and magnetic field B\mathbf B, and it comes out without any change in velocity. The possible cases are: (1) E=0\mathbf E=0 and B≠0\mathbf B\ne0 (2) E≠0\mathbf E\ne0 and B=0\mathbf B=0 (3) E≠0\mathbf E\ne0 and B≠0\mathbf B\ne0 (4) E=0\mathbf E=0 and B=0\mathbf B=0
