Find the radius of the circular path described by a proton moving at 15 in a plane perpendicular to a 400- magnetic field.

2. Relevant equations

I used the Eqn: r=mv/qB

So (1.67e-27)(15ooom/s)/(1.60e-19)(400) and I go 6.265e-2 m

but the answer is in mm so im i correct to just say 6.265e-5

since mm is e-3 and its alrdy e-2m

is my answer even right though?
