Which of the following combinations of particle charge q and velocity ī, in a magnetic field B, corresponding to a magnetic force FB, is invalid? Consider the N-E-W-S direction system, with up as going away from the ground and down as going into the ground. (A) q < 0,ữ : going north, B : directed to west, FB : downward (B) q> 0,ỡ : downward, B : directed to north, FB : directed to east (C) q < 0,ỡ : upward, B : directed to south, FB : directed to east (D) q < 0, ữ : going east, B : directed to north, FB : downward (E) q < 0,& : going east, B : directed downward, Fp : directed to south
