A beam of protons is moving in the +x direction with a speed of 13 km/s through a region in which the electric field is perpendicular to the magnetic field. The beam of protons is not deflected in this region. The magnetic field has a magnitude of 0.8 T and points in the +y direction. Therefore, the magnitude of the electric field is 11.570 V/m (= (13 x 10³ m/s) (0.8T)) and the direction is along the negative z-axis.

What are the x-, y- and z-component of the electric field?
