The figure shows a particle with positive charge q = 6.40 x 10-19 C moving with speed v = 8.13 x 105 m/s toward a long straight wire with current i = 229 mA. At the instant shown, the particle's distance from the wire is d = 1.77 cm. What is the magnitude of the force on the particle due to the current?
