The figure shows an arrangement of four charged particles, with angle = 35.0° and distance d = 1.50 cm. Particle 2 has charge 92 = 9.60 × 10-1⁹ C; particles 3 and 4 have charges 93 94 = -4.80 × 10-19 C. (a) What is the distance D between the origin and particle 2 if the net electrostatic force on particle 1 due to the other particles is zero? (b) If particles 3 and 4 were moved closer to the x axis but maintained their symmetry about that axis, would the required value of D be greater than, less than, or the same as in part (a)?
