At time t1, an electron is sent along the positive direction of an x axis, through both an electric field E and a magnetic field B, with E directed parallel to the y axis. Figure gives the y component F net, y of the net force on the electron due to the two fields, as a function of the electron's speed v at time t1. The scale of the velocity axis is set by vx = 100.0 m/s. The x and z components of the net force are zero at t l. Assuming Bx = 0, find

(b) B in unit-vector notation
