advanced physics problem

An electron travels in a uniform magnetic field. The following three diagrams show the electron's velocity and magnetic field projected onto the three axis-planes (i.e. exactly the same situations from three views). The magnitude of the magnetic field is (4.8000x10^-3) T. The velocity components of the particle is vy = (5.500x10^2) m/s and Vz = (-1.20x10^3) m/s. What is the magnitude of the magnetic force that acts on the electron? Provide your answer in newtons (N) using scientific notation with 3 significant figures. B B B V' V' Z X X Note: Your answer is assumed to be reduced to the highest power possible
