PLC Activity #1 Coulomb’s Law Due: see website for due date How to get credit for this activity First, sign-in into your attendance sheet and sign-out when the activity is complete. Show your work and results to a PLC tutor so they can check your work and initial the signoff sheet. Be prepared to answer questions about the activity or your results. Question 1 The figure below shows four situations in which charged particles are fixed in place on an axis. In which situations is there a point to the left of the particles where an electron will be in equilibrium (i.e. the net force on it will be zero)? Question 2 Given below are arrangements of three fixed electric charges. In each figure, a point labeled P is also identified. All of the charges are the same size charge, q, but they can be either positive or negative as indicated. The charges and point P all lie on a straight line. The distances between adjacent items, either between two charges or between a charge and point P, are all the same. There are no other charges in this region. A test charge, +Q, is placed at point P. a. Rank these arrangements from greatest to least on the basis of the strength (magnitude) of the electric force on the test charge, +Q, at P. b. Please carefully explain your reasoning.
