A charged particle is circling a magnetic field that gradually increases in magnitude from \(B_{1}\) to \(B_{2}\) as the particle advances along the field lines. Show that the particle will be reflected if

where \(v_{0 \|}\) and \(v_{0 \perp}\) are the components of the particle's velocity parallel and perpendicular to the magnetic field.
