In the figure four particles form a square with edge length a = 4.68 × 10-2 m. The charges areq1 = q4 = 1.49 × 10-15 C and q2 = q3 = q.
(a) What is q if the net electrostatic force on particle 1 is zero?
(b) Is there any value of q that makes the net electrostatic force on each of the four particles zero?
