Proton charge: +1.66x18-1QC, Proton mass: 1.6?x10n-27 kg Electron charge: -1.6@x10A-19C, Electron mass: 9.11x10-31 kg Coulomb's constant: 9.00x10A9 NmAZ/CAZ QUESTION 1 (20 marks) An electron feels four electric forces: The electron is 23.4mm[N] from a charge of negative 9.47xiGn-14 C The electron is S?.8mm[E] from a charge of positive 9.47x18n-14 C The electron is 3?.8mm[5] from a charge of negative 9.47x18n-14 C The electron is 23.4mm[W] from a charge of positive 9.47x10n-14 C Calculate the acceleration of the electron. Remember to include direction. The effects of gravity are negligible and can be ignored. QUESTION 2 (8 marks) A proton is travelling at a velocity of 5860 m/s [23.9 degrees 5 of w]. It enters a magnetic field of 2.14 T [36.7 degrees w of N]. (4 marks) Calculate the magnitude of the magnetic force on the proton. (1 mark) Is the force on the proton up or down? (1 mark) If the proton was replaced with an electron at the same velocity, would the force be up or down? (1 mark) If the proton was replaced with an electron at the same velocity, would the magnitude of force change? (1 mark) If the proton was replaced with an neutron at the same velocity, would the force be up or down? {139.0593 QUESTION 3 (12 marks) A molecule of charge 1.69x10A-19 C is placed on the positive end of a parallel plate setup. The molecule accelerates from rest and exits through a small hole in the negative plate. The molecule then maintains its velocity as it enters a magnetic field of 1.88 T[Up]. The molecule enters the magnetic field at a velocity of 5.37x104 m/s[E]. In the magnetic field, the molecule has a turning radius of 8.42 cm. The angle between the molecule's velocity and the magnetic field is exactly 90 degrees. During the molecule's circular motion, it experiences no other forces other than the magnetic force. a (4 marks) Calculate the magnitude of the acceleration of the molecule as it travels in the circle. b (4 marks) Calculate the mass of the molecule. c (4 marks) Calculate the potential difference (voltage) of the parallel plate setup
