An electron with a mass of 9.1 x 10-31 kg and a charge of - 1.6 x 10-19 C travels in a circular path with no loss of energy in a magnetic field of 0.05 T that is orthogonal to the path of the electron. If the radius of the path is 0.003 m, what is the speed of the electron? The speed of the electron is 6x 106 m/s.
