(6 marks) A 3. 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. Weight (X 10-" N) Electric Field Strength (x 10 N/C) 1.7 1.1 5.6 3.5 6. 1 3.8 2.9 1.8 4.0 2.5 Graph the recorded data. Using ONLY the graph, determine the elementary charge. 2009 Alberta Education
