An electron in a vacuum is first accelerated by a voltage of 21100 V and then enters a region in which there is a uniform magnetic field of 0.644 T at right angles to the direction of the electron’s motion. The mass of the electron is 9.11 × 10−31 kg and its charge is 1.60218 × 10−19 C. What is the magnitude of the force on the electron due to the magnetic field?
Answer in units of N.
