A beam of protons is directed in a straight line along the positive z-direction through a region of space in which there are crossed electric and magnetic fields. If the electric field magnitude is E = 430 V/m in the negative y-direction and the protons move at a constant speed of v = 8.7 x 10° m/s, what must the direction and magnitude of the magnetic field be in order for the beam of protons to continue undeflected along its straight-line trajectory?
