Physics 272Lab Lab 3: Charge on Tape Lab #3 – Charge on Tape OBJECTIVES In this lab you will: Design an experiment to calculate the amount of charge on a piece of tape Make physical measurements and modeling assumptions Calculate physical quantities based on the above measurements Verify your results to be physically reasonable 1) Warm-Up Problems The following problems are intended to motivate a possible experimental design for measuring the charge on a piece of invisible tape. After you have taken all necessary data (for your experiment) you will do calculations similar to those you are about to do in these problems. Therefore, to save your group a great deal of time in this lab, we advise that you SOLVE THE PROBLEMS BELOW ENTIRELY SYMBOLICALLY . This symbolic approach will provide you with a formula in which to enter your experimental data. Problem (1) Two small plastic balls (of mass ± ² ³ ´ ) are rubbed all over with fake fur – both acquiring the same amount of charge. Attached to each ball are insulating nylon strings, which are arranged so that the balls may only move up or down in the vertical direction. When one ball is held above the other as shown, the top ball “floats” a distance µ ² ¶·¸ ¹± above the lower ball, and the
