Three charges of 1 nC , 2 nC and 3 nC are placed at the corners of an equilateral triangle of side 3 . Calculate electrostatic potential at a point equidistant from the three corners of the triangle.

l 1 = l 2 sec 30 ° = l 3 ⇒ V 0 = kq 1 l 1 + kq 2 l 1 + kq 3 l 1 = k l 1 ( q 1 + q 2 + q 3 ) = 3 k l q 1 + q 2 + q 3
