Please solve this question in details and fully explaination. Thank you so much in advance.

2 . The figure shows an arrangement of 4 charged particles, with angle D= 30.0 and distance d= 2.00 cm. Particle 2 has charge 9, = + 8.00 x 10- C ; particle 3 and 4 have charges 93 = 9 = - 1.60 x 10 "C -19 What is the distance D between the origin and particle a if the net electrostatic force on particle I due to the other particles is zero . Assume that the charge of particle 1 is positive - Please solve by first create the free -body diagram for particle 1 . D 1 4
