Here +4uC and +4uC will cancel effect of each other as both are diagonal opposite and hence electric field at center will be due to +3 uC and -3uC charge
Now E = kQ1/r^2 +kQ2/r^2
Here r = 1/sqroot2 so r^2 =1/2
So E = 3×10^-6×9×10^9/(1/2) +3×10^-6×9×10^9/(1/2)
E = 2×(3×10^-6)×9 ×10^9/(1/2) = 1.08×10^5 N/C
Or E = 1.1 × 10^5 N/C
Hence option E is correct
