Three charged particles form a triangle: particle 1 with charge Q1 = 91.0 nC is at xy coordinates (0, 4.70 mm), particle 2 with charge Q2 is at (0, -4.70 mm), and particle 3 with charge q = 46.0 nC is at (7.20 mm, 0). What are (a) thex component and (b) the y component of electrostatic force on particle 3 due to the other two particles if Q2 is equal to 91.0 nC? What are (c) the x component and (d) the y component of electrostatic force on particle 3 due to the other two particles if Q2 is equal to -91.0 nC, ? In the figure four particles form a square. The charges are q1 = +Q, q2 = 93 = q, and q4 = -7.00Q. What is q/Q if the net electrostatic force on particle 1 is zero
