Question

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?
