Question

Three charges, q1 = +2.5 μC, q2 = -3.6 μC, and q3 = -5.0 μC, are located at the corners of an equilateral triangle with sides of length 0.5 m centered at the origin. The corner locations are at (-0.250 m, -0.145 m), (+0.250 m, -0.145 m), and (0 m,+0.290 m) respectively.

Part 1: What is the magnitude of the net ELECTRIC FORCE on the +2.5 μC charge?

Part 2: Which of the following is a correct expression for the net ELECTRIC FIELD at the center of the triangle (the origin)? Here, r₁, r₂, and r₃ stand for the distances from the origin to each charge.
