11. When a charged particle moves with velocity v through a magnetic eld B, a force due to the magnetic eld FB acts on the charged particle. This occurs according to the crossproduct: FB = qv x B Where q is the charge of the particle. (a) If a particle of charge (1 = 13.4 X 1060, where the unit C is a Coulomb, moves according to the velocity vector v = (1,5,2) and the magnetic eld vector is B = (4, 2, 1>, nd the force vector FB that is acting on the particle. (b) What is the magnitude of the force on the particle? (0) Sketch the righthanded system {v, B, FE} and roughly indicate the trajectory of the particle
