Consider an electron, accelerated by a potential difference of 260 V. After the acceleration, the electron is moving with a constant speed perpendicularly to a uniform magnetic field of 0.0001 T. Determine the radius of its trajectory in the magnetic field. Electron charge and mass are 1.6e-19 C and 9.11e-31 kg, respectively.
