Laboratory scientists have created the electric and magnetic fields shown in the figure.(Figure 1) These fields are also seen by scientists that zoom past in a rocket traveling in the x-direction at 1.0×10^6m/s. Assume that B = 0.58 T and E = 1.3×10^6 V/m . According to the rocket scientists, what angle does the electric field make with the axis of the rocket?
