Describe the electron's subsequent circular motion

[jan2905]

An electron (mass=m, charge=-e) is projected with speed v upward, in the plane of the page, into a region containing a uniform magnetic field B, that is directed into the plane of the page. Describe the electron's subsequent circular motion.

I tried using the Right-Hand Rule.

I said: Clockwise rotation; radius of path = mv/(eB). Is this correct?

Yes.
