Dean is hunting in the Northwest Territory at a location where the earth's magnetic field is 8.0x 10^-5 T. He shoots at a duck decoy by mistake, and the rubber bullet he is using acquires a charge of 3.0 x 10 ^ -12 C as it leaves his gun at 300m/s, perpendicular to the earth's magnetic field. What is the magnitude of the magnetic force acting on the bullet?
