The drawing shows a parallel plate capacitor that is moving with a speed of 20 m/s through a 5.0-T magnetic field. The velocity is perpendicular to the magnetic field. The electric field within the capacitor has a value of 200 N/C, and each plate has an area of 5.0 x 10^-4 m^2. What is the magnetic force (magnitude and direction) exerted on the positive plate of the capacitor?
