A small metal ball with a charge of 0.05 C and a mass of 25 g (0.025 kg) enters a region where there is a magnetic field of 0.5 T. The ball is traveling with a velocity of 200 m/s in a direction perpendicular to the magnetic field, as shown in the diagram. Centripetal acceleration is equal to v²/r, what is the radius of the curve the ball will move through under the influence of the magnetic force?
