6-(20 pts.) Consider an inertial frame S' moving with velocity relative to another inertial frame S. The motion is such that the axes in S and S' remain parallel, but the velocity of S' in frame S is in an arbitrary direction. In S, consider a static, uniform electric field = E and a static, uniform magnetic field B = 2(E/c)(cos 6 + sin @ ). Determine the relative velocity of S' in which the electric field ' and the magnetic field ' are parallel. Explicitly determine the electromagnetic fields in S'when 0 + 7/2. 6-(20 pts.)
