Go At time t1 an electron is sent along the positive direction of an x axis, through both an electric field and a magnetic field with directed parallel to the y axis. Figure 28-33 gives the y component Fnet,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 vs = 100.0 m/s. The .x and z components of the net force are zero at t1. Assuming Bx = 0, find (a) the magnitude E and (b) in unit-vector notation.
