The mass of the electron is 9.11 X 10RS ke and its charge is 1.60218 x 107" C. What is the magnitude of the force on the clectron due to the magnetic field? 1. 1.55469 x 1072 2. 3.86459 x 10712 3.1.0188 x 1071 4.1.34981 x 10~ 5. 2.70077 x 10~ PIHY2 Exam_3A 23-24 tojeda (CootsKPl 1Y 2_L) 6. 6.76687 % 10~ 7.1.43375 % 107" 8. 1.20657 % 1074 9. 5.85766 x 10~ 10. 1.74168 x 107" Answer in units of N. 003 10.0 points In an experiment designed to measure the strength of a uniform magnet ic field produced by a set of coils, electrons are accelerated from rest through a potential difference of 275 V. The resulting electron beam travels in a circle with a radius of 3.92 cm, The charge on an electron is 1.60218 % 10~9 C and its mass is 9.10939 X 1073 kg. Assuming the magnetic field is perpendic- ular to the beam, find the magnitude of the magnetic field. 1. 0.00142654 2. 0.000543018 3. 0.000709004 4. 0.000514631 5. 0.000602684 6. 0.000443762 7. 0.000485228 8. 0.000449898 9. 0.000357464 10. 0.000723985 Answer in units of T. 004 10.0 points At what distance from a long, straight wire carrying a current of 5 A is the magnetic
