A 3.25 g bullet picks up an electric charge of 1.55 µC as it travels down the barrel of a rifle. It leaves the barrel at a speed of 423 m/s traveling perpendicular to the earth's magnetic field, which has a magnitude of 5.50×10?4 T.

Part A: Calculate the magnitude of the magnetic force on the bullet.

F = ?

Part B: Calculate the magnitude of the bullet's acceleration due to the magnetic force at the instant it leaves the rifle barrel.

a = ?
