Suppose that the magnetic field has a magnitude of 0.130 T, the particle's speed is 6.0 multiplied by 106 m/s, and the radius of its path is 144.5 cm. Find the mass of the particle, given that its charge has a magnitude of 1.60 multiplied by 10?19 C. Give your result in atomic mass units, u, where 1 u = 1.67 multiplied by 10?27 kg.
