Six point charges are arranged on a plane as shown in Fig. 2. The potential (V) of this arrangement is zero at infinite distance. The charges are as follows: q1 = 5.0q, q2 = −2.0q, q3 = −3.0q, q4 = +3.0q, q5 = −2.0q and q6 = +5.0q. Find the net electrostatic potential V at the central point P. Fig. 2
