Two identical metal balls are suspended by insulating threads as shown in Figure 1. Both balls have the same net charge. In this problem, do not assume the balls are point charges. Ball 1 Ball 2 a. Draw a free-body diagram for each ball (include a key): Now suppose the charge on the ball 2 is reduced slightly, so that it is less than that on ball 1. b. The angle that ball 1 makes with the vertical will be greater than, less than, or equal to [circle one] the angle that ball 1 makes with the vertical in part (a). Explain, including a sketch. c. The angle that ball 1 makes with the vertical will be greater than, less than, or equal to [circle one] the angle that ball 2 makes with the vertical. Explain, including a sketch.
