An electron moves in a force field due to a uniform electric fied E=E(i+j) and a uniform magnetic field B=Bk. Take the initial position of the electron at the origin with initial speed Vo=Vox i in the x direction. Find expressions for the cycloidal path of the resulting motion of the electon, i.e., what are x, y,z positions?
