1. The problem statement, all variables and given/known data An electron moves through a uniform magnetic field given by B = Bx i + (3.68 Bx) j . At a particular instant, the electron has velocity v = (1.88 i +4.86 j) m/s and the magnetic force acting on it is (2.43 × 10-19) N. Find Bx. Givens B = [Bx i + (3.68 Bx)] v = (1.88 + 4.86) Fb = (2.43 × 10-19) N. Find Bx. 2. Relevant equations Fb = q(B x V) 3. The attempt at a solution (2.43 x 10^-19)k = (1.602 x 10^-19) [(Bx i + (3.68Bx) j) x (1.88 i + 4.86 j) cross product resultant: (2.43 x 10^-19)k = (1.602 x 10^-19) (-2.06*Bx)k (2.43 x 10^-19)k = (-3.30 x 10^-19*Bx) k I don't understand how to solve for the Bx, we haven't learned how to divide vectors, and I can't really pull the Bx out of the k vector as a scalar. How do I solve for the Bx???
