Q277
A uniform and constant magnetic field B = zB exists in the z direction in vacuum. A particle of mass m with a small charge q is introduced into this region with an initial velocity v = xv_x + zv_z. Given that B, m, q, vx and vz are all non-zero. Which one of the following describes the eventual trajectory of the particle?
