no it is wrong

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. The figure gives the y component Fnety 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 = 110 m/s. The x and z components of the net force are zero at t1. Assuming By = 0, find (a) the magnitude of the electric field and (b) B in unit-vector notation. Fnet,y (10-19 N) 0 0 -1 -2 v (m/s) (a) Number 1.25 Units N/C or V/m (b) 0 i+ i -0.0227 k Units T
