(a) Prepare a charged strip of transparent tape as described in Figure 22.3 and then suspend the strip from the edge of your desk. Verify that the tape interacts as you would expect with your hand, with a strip of paper, and with another charged strip of tape.

(b) Rub your fingers along the hanging strip to remove all the charge from it, and then verify that it no longer interacts with your hand. If it does interact, rub again until it no longer interacts.

(c) Predict and then verify experimentally how the uncharged suspended strip interacts with a strip of paper and with a charged strip of tape.

Figure 22.3 Procedure for making strips of transparent tape that interact electrically. The purpose of the foundation strip is simply to provide a standard surface. On flat surface, stick down tape strip as foundation: flatten with thumb. Fold end of second strip to make handle; smooth onto foundation strip. 3 Pull second strip off in one quick motion. Holding both ends of strip to prevent curling, hang strip on table edge. foundation strip
