Question

55. 11 You have two small, 2.0 g balls that have been given equal but opposite charges, but you don't know the magnitude of the charge. To find out, you place the balis distance d apart on a slippery horizontal surface, release them,and use a motion detector to measure the initial acceleration of one of the balls toward the other. After repeating this for several different separation distances, your data are as follows: Acceleration (m/s2) Distance (cm 2.0 3.0 4.0 5.0 0.74 0.30 0.19 0.10 Use an appropriate graph of the data to determine the magnitude of the charge.
