You wish to hit a target from several meters away with a charged coin having a mass of 4.4 gram and a charge of +2700 μC. The coin is given an initial velocity of 12 m/s, and a downward, uniform electric field with field strength 25 N/C exists throughout the region.
Part A. If you aim directly at the target and fire the coin horizontally, find what magnitude of uniform magnetic field is needed in the region for the coin to hit the target?
