A 30.0-g metal ball having net charge Q = 4.60 µC is thrown out of a window horizontally north at a speed v = 21.2 m/s. The window is at a height h = 19.8 m above the ground. A uniform, horizontal magnetic field of magnitude B = 0.0100 T is perpendicular to the plane of the ball's trajectory and directed toward the west. (a) Assuming the ball follows the same trajectory as it would in the absence of the magnetic field, find the magnetic force acting on the ball just before it hits the ground. (Let the +x-direction be toward the north, the +y-direction be up and the +z-direction be east.)
