Trina makes a diagram to summarize how to use the right-hand rule to determine the direction of the magnetic force on each type of charge. which labels belong in the regions marked x, y, and z? a) x: thumb, for velocity y: fingers, for magnetic field z: palm of hand, for force b) x: back of hand, for force y: thumb, for velocity z: palm of hand, for force c)x: palm of hand, for force y: thumb, for velocity z: fingers, for magnetic field d) x: palm of hand, for force y: fingers, for magnetic field z: back of hand, for force
