A 1.00 kg metal ball having net charge Q = 5.99 uC is thrown out of a window horizontally at a speed v = 15.4 m/s. The window is at a height h = 18.9 m above the ground. A uniform horizontal magnetic field of magnitude B = 0.0200 T is perpendicular to the plane of the ball's trajectory. Find the magnitude of the magnetic force acting on the ball just before it hits the ground. (Hint: Ignore magnetic forces in finding the ball's final velocity.) Please Show work.
