1. Uniform electric and magnetic fields are oriented at right angles and perpendicular to each other. An electron moves at right angles to both the fields and passes undeflected through the field. If the magnitude of the electric filed intensity is 2000 V/m, determine the value of magnetic flux density and magnetic field intensity (assume free space conditions).
