    Two identical positive point charges (q1 = q2 = +2.00 nC) are placed at the bottom two vertices of an equilateral triangle of edge length 5.00 cm. One negative point charge (q3= -3.00 nC) is placed at the apex. (a) Calculate the electrical potential produced by the combination of all three point charges together at the midpoint of the base of the triangle. (Remember that each angle in an equilateral triangle is 60 degrees.) (Answer: 816 V) (b) Calculate the...
