In the figure, the four particles are fixed in place and have charges q₁ q2 = +20, q3= +60, and q4= -40. In terms of k, Q, and d, what is the magnitude of the net electric field at point P due to the four particles? Include a diagram of the situation indicating the electric field vectors acting at the point P. 91 42 94
