Unformatted text preview: Version 001 HW12 gavrin (25111) 1 This print-out should have 10 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. Electron in a Magnetic Field 001 10.0 points An electron in a vacuum is first accelerated by a voltage of 1 . 019 10 5 V and then enters a region in which there is a uniform magnetic field of 0 . 136 T at right angles to the direction of the electrons 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? Correct answer: N. Circular Orbit of a Proton 002 10.0 points What is the radius of the smallest possible cir- cular orbit that a proton with energy 2 . 6 MeV can have in a 3 T magnetic field? The mass of a proton is 1 . 67 10 27 kg and its charge is 1 . 609 10 19 C....
