An electron moves on a circular orbit in a uniform magnetic field. The strength of the field is 1.00ื10-5 tesla. The kinetic energy of the electron is 178.0 eV. (1 eV = 1 electron volt = 1.6 ื10−19 joules.) Calculate the radius of the orbit.
(electron parameters: the charge is -e where e = 1.602ื10-19 C; the mass is m = 9.11ื10-31 kg.)
