1. Three objects each with charge Q and mass M are placed a distance L apart to form an equilateral triangle. (a) Calculate the force between any two of the objects. (b) Calculate the electric field at the center of the triangle (explain your reasoning). (c) Calculate the electric potential at the center. (d) Calculate the net electric potential energy of the system of charges. (e) If the charges are released, what will be the velocity of the objects once they have separated by several meters? (All of the potential energy will have become kinetic energy.) Q = 1100 C M = 259 L = 20 cm 0 L 2. A thin rod of length L has a charge Q distributed uniformly along its length. Derive an expression for the electric potential at point P, a distance x from the end of the rod. L- -x- P 1.
