A very humble bumble bee is flying horizontally due North at a constant speed of 3.11 m/s. At the current location of the bumble bee the magnetic field of Earth is 1.05×10-5 T and it points 35.1° below the horizontal. The bumble bee carries a positive electric charge of 22.5 nC. What is the size of the magnetic force acting on the bumble bee?
