You wish to hit a target from several meters away with a charged coin having a mass of 5.4 g and a charge of +2400 Mc . The coin is given an initial velocity of 13.0 m/s , and a downward, uniform electric field with field strength 28.0 N/C exists throughout the region.

If you aim directly at the target and fire the coin horizontally, what magnitude of uniform magnetic field, perpendicular to the velocity, is needed in the region for the coin to hit the target?
