Question: Show that a charged particle moving in the plane perpendicular to a constant magnetic field (eq. (19.29) moves in a circle with Br = mv/q.

Show that a charged particle moving in the plane perpendicular to a constant magnetic field (eq. (19.29)

moves in a circle with Br = mv/q. What is the radius of the circle for an electron with energy 15 keV in a 10 Tesla magnetic field (typical of ITER)? What is the radius for a proton?

F = qE + qv x B +qv
