1) Two strips of tape (strip A and B) are initially stuck together and neutral. After being ripped apart 2.2 x 10#* electrons are removed from strip A a) What is the electric charge of strip A? What is the electric charge of strip B? c) What law guarantees your answer? 2) How far apart are 2 electrons if they have a repulsive force of 1.0 N between them? (charge on an electron is -1.6 x 10-19) 3) Draw the electric field lines between two equal and negatively charged particles. Show 8 lines on each charge and space them approximately 2 inches apart. 4) Use the diagram below to solve for the electric field at point x -8:10-C cm 4em
