Use the following constants if necessary. Coulomb constant, k = 8.987 x 10° N - m?/C2. Vacuum permitivity, en = 8.854 x 10-12 F/m. Magnitude of the Charge of one electron, e = -1.60217662 x 10-19 C. Mass of one electron, m, = 9.10938356 x 10-31 kg. Unless specified otherwise, each symbol carries their usual meaning. For example, uC means micro coulomb. as a i a 93 Mark distribution: 3+4+3 a) Calculate how much work is required to set up the arrangement if the charges are initially infinitely far apart and were at rest. (Hint: Use the relation between work done by external agent and total electric energy of the system) Here a = 19 cm, b = 9 cm and the three charges are gl = 30 µC, g2-25 μC4320 μC Work done Give your answer to at least three significance digits. joules b) Calculate the potential at the controid(point p) of the triangle. Potential at the centroid Give your answer to at least three significance digits. volts
