Explanation / Answer

the electric force = F = k q1 q2/d2
1. F2 = F12 + F13

here F12 and F13 are of same magnitude and will act in same direction (towards left), hence will add

so F2 = 2* F12 =

2*9*109 *2.8 * 10-6*2.8 * 10-6 / (1.5*10-3)2 = 62633.24 N

2) here the direction of F12 and F13 are opposite and magnitude is same,

hence net force is zero

3)here it will be the vector sum of F12 and F32.

so F2= square root of (31316.32)2 + (31316.32)2 = 44288.388 N
