Consider three charges arranged in a triangle as shown in the figure: Q = 36 C h = 4 cm d = 3 cm Q2 = Q 194.4 J = d 0 d h Q = Q How much work is done by you to assemble these charges from infinitely far apart to the above configuration? (a) W = -194.4 J (b) W = 0 J (c) W (d) W = 5.4 J (e) W = -38.88 J Q3 Calculate the electric potential created by these three charges at point O located between charges Q2 and Q3. (a) Vo 8100 kV (b) Vo = 0 kV (c) Vo = -8100 kV
