The diagrams in Figure 15.97 show a sequence of events involving a small lightweight aluminum ball that is suspended
from a cotton thread. In order to get enough information, you will need to read through the entire sequence of events
described below before beginning to answer the questions. Before trying to select answers, you will need to draw your own
diagrams showing the charge state of each object in each situation.
(a) A small, lightweight aluminum ball hangs from a cotton thread. You touch the ball briefly with your fingers, then release it (Diagram 1 in Figure 15.97). Which of the diagrams in Figure 15.98 best shows the distribution of charge in and/or on the ball at this moment, using the diagrammatic conventions discussed in this chapter?

of charge in and/or on the ball at this moment?
(c) The ball briefly touches the charged metal block (Diagram 4 in Figure 15.97). Then the ball swings away from the
block and hangs motionless at an angle, as shown in Diagram 5 in Figure 15.97. Which of the diagrams in Figure
