Three point-like charges: q1 = 7.5 μC, q2 = 2.8 μC and q3 = −9.3 μC, are positioned at the corners of an equilateral triangle with side length L = 3 cm shown in the figure Find electrostatic forces F1, F2 and F3 exerted on each of the respective charges in terms of their components with respect to shown axes: F1x = N, F2x = N. F1y = N, F2y = N. F3x = N, F3y = N. Check if your numerical results (at least approximately) agree with the statement that the total force F = F1+F2+F3 exerted on this whole system must be zero.
