An electron moves in a circular orbit of radius r in a magnetic field. The electron moves in a path perpendicular to the magnetic field. If the kinetic energy of the electron is doubled, what is the new radius of its path?
What formula would I use to go about this? Is this about mass spectrum? So I would go about using Fnet=ma, and then Fb (of a single charge) = mv^2/r. So Bvq = mv^2/r... then where? Please help! Test tomorrow! :(
