A unifоrm mаgnetic field оf mаgnitude 0.80 T in the negаtive z-directiоn 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?
