A particle of mass m and charge q is in a region with a constant B-field in the x-direction, B~ = Bxˆ. The initial velocity of the particle is ~v = v0xxˆ + v0yyˆ. The particle moves in a helix. (a) Show that the radius of the helix is r = mv0y/(qB) (b) Show that the time to complete one rotation in the helix is τ = 2πm/(qB)
