An electron undergoes a transition from the 3rd energy level to the 1st energy level in a hydrogen atom. The wavelength of the radiation associated with this transition is a.bc x 10-d m. Record abcd. Selected Energy Levels for Hydrogen -0.544 eV -0.850 eV =2 -1.51 eV -3.40 eV Question 11 (2 points) Use the following information to answer the next two questions: During a Millikan oil drop experiment, a student records the weight of five different droplets. A record is also made of the electric field intensity needed to hold each droplet stationary between the horizontal charged plates. Table A Electric Field Weight Strength (x105 N/C) (x10-14N) 1.1 1.7 3.5 5.6 3.8 6.1 1.8 2.9 2.5 4.0 Graph the recorded data (do on your own, does not need to be submitted but needs to be done in order to answer this question). Using only the graph, the value of the elementary charge is a.bc x 10-19 C. After writing your answer in scientific notation, round your answer to have two places after the decimal. To not include the 10-19 in your answer. For example, if your answer is 1.234 x 10-19 C, you would type 1.23 into the answer box. Question 15 (2 points) An unknown particle travelling with a velocity of 3.12 x 105 m/s enters a 54 mT magnetic field and curves in a circular path with a radius of 12 cm. Determine the charge-to-mass ratio, enter that value in the first blank (with three significant figures of accuracy). From the table of particles on your data sheet, the identity of the unknown particle is most likely Blank # 1 Blank # 2 Question 21 (1 point) An oil drop weighs 1.66x10-14 N. It is suspended in a Millikan two plate apparatus where the electric field strength is 1.30x104 N/C. The charge on the oil drop is a.b x 10d C. Input your answer for in the blank. For example, if your answer 3.2 x 10-19 C, you would input 3219 in the blank. Use the data sheet values for constants, charges, masses etc. Do not include units.
