Four charges equal to \( -Q \) each are placed at the
P four corners of a square and a charge \( q \) is at its

W centre. If the system is in equilibrium, the value of \( q \) is:
(A) \( -\frac{Q}{4}(1+2 \sqrt{2}) \)
(B) \( \frac{Q}{4}(1+2 \sqrt{2}) \)
(C) \( -\frac{Q}{2}(1+2 \sqrt{2}) \)
(D) \( \frac{Q}{2}(1+2 \sqrt{2}) \)
