An electron has velocity $=(36+38)$ km$/$s as it enters a uniform magnetic field $=61$T$.$

$($a$)$ What is the radius of the helical path taken by the electron?

mm

$($b$)$ What is the pitch of that path?

mm

$($c$)$ To an observer looking into the magnetic field region from the entrance point of the electron, does the electron spiral clockwise or counterclockwise as it moves?
