A 3.25 g bullet picks up an electric charge of 1.85 μC as it travels down the barrel of a rifle. It leaves the barrel at a speed of 445 m/s traveling perpendicular to the earth’s magnetic field, which has a magnitude of 5.50×10⁻⁴ T .
Calculate the magnitude of the magnetic force on the bullet.
Calculate the magnitude of the bullet’s acceleration due to the magnetic force at the instant it leaves the rifle barrel.
