Holding these two strips togeather they will repel each other. Assume the average lencth (10cm) of the tapes is half their actual length. The distance that they repel each other is 7cm. Assume each strip of tape has a mass of 0.1g. Assume both strips were equally charged and the charge is located at the middle of the strip. Calculate an order of magnitude value for the number of excess electrons on one strip of tape. show calculations.
