Problem

Adding the fields * A stationary proton is located on the zz axis at z=az = a. A negative muon is moving with speed 0.8c0.8c along the xx axis. Consider the total electric field of these two particles, in this frame, at the time when the muon passes through the origin. What are the values at that instant of ExE_x and EzE_z at the point (a,0,0)(a, 0, 0) on the xx axis?
