Velocity selector: A uniform magnetic field of magnitude 0.80 T in the negative z-direction is present in a region of space, as shown in the figure. A uniform electric field is also present. An electron that is projected with an initial velocity in the positive x-direction passes through the region without deflection. What is the electric field vector in the region?
