The uniform $32\mathrm{.}0$ mT

magnetic field in the figure points in the positive z$-$direction. An electron enters the region of magnetic field with a speed of $4\mathrm{.}70\backslash$times $106$m$/$s

and at an angle of $30$

above the xy$-$plane. $($Figure $1)$

Figure$1$ of $1$

An electron travels through a magnetic field pointing upward in the positive z direction. The electron has an initial velocity pointing $30$ degrees above the y$-$axis in the y$-$z plane. The electron travels upward in a spiral pattern with radius r and pitch p$.$
