1. What did you observe about the magnitudes of the forces on the two charges. Were they the same or different? Does your answer depend on whether the charges were of the same magnitude or different? How does this relate to Newton's 3"d law? 2. What did you observe about the directions of the two forces? How did the directions depend on the signs of the charges? 3. Print your three graphs. 4. The graph of force vs. qiq2 should be linear. To fit a line to this data, click and drag the mouse across the linear region, then click Linear Fit, 4. Combine the slope of the line with the value of r in order to obtain the value (plus units) of the Coulomb law constant. 5. What was the function of r that resulted in your third graph being linear? 6. Combine the slope of this graph with the values of qi and q2 to again obtain the value (plus units) of the Coulomb law constant
