Charged particles 1, 2, and 3 (q1 = 5.0 mC, q2 = -4.00 mC, and q3 = -3.00 mC) are arranged at the vertices of a square of side 1 m, with particles 2 and 3 occupying opposite vertices. Determine the position of particle 4, carrying the same charge as particle 1, such that the total electric force on particle 1 is zero.
