Question
Here is a reproducible procedure for making an "L" tape, whose charge is unlike the charge of a U tape: Stick a new strip of tape, with a handle at one end, down onto a ha.se tape that is stuck down on the desk. Smooth it down with your thumb or fingertips, and write L on its handle. Then stick another strip with a handle on top of the L tape, smooth it down, and write U on its handle. Slowly lift the L tape, bringing the U tape along with it (and leasing the bottom base tape stock to the desk). Hang the double layer of tape vertically from the edge of the desk and see whether there is attraction between it and your hand. If so, get rid of these interactions (hold the bottom of the tape and slowly rub the slick side with your fingers or thumb). Check that the tape pair is no longer attached to your hand. THIS IS IMPORTANT! Hold onto the bottom tab of the L tape and quickly pull the U tape up and off. Hang the U tape vertically from the edge of the desk, not too close to the L tape! Repealing exactly the same procedure, make another pair of tapes to that you have at least two U tapes and two L tapes. Before separating the tapes from each other, remember to run your finger along the slick side of the tape pair to get rid of interactions with your hand. If an L tape is indeed vertically charged, and its charge is unlike the charge on a U tape, what interaction would you predict between an L tape and a U tape? Make sure that both the UY tape and the L tape are active (attracted to your hand). What interaction do you observe between an L tape and a U tape?Explanation / Answer
i) For the first one its repulsion due to which it is directed away
ii) for second one there is no interation between the tape as there is no change in position
iii) since the tape is folded towards the other one so we can say that there is attraction between the two ends of tape in this position
