2) Constant magnetic field B is in x direction. At time t=0 a proton of charge e and mass m is located at the origin and has velocity vector (v, 2v,0). a) What is the name of the curve that the proton follows? b) What is the radius of this curve? c) What is the pitch of this curve? d) Find the direction of the axis of this curve. e) Find coordinates of a point through which the axis of the curve passes.
