A rod is hinged at its centre \( O \) and free to rotate about a horizontal axis of rotation as shown in figure-1.430. Two point
P charges \( +q \) and \( +q \) are fixed at the two ends of the rod. A

W uniform electric field \( E \) exist in the region toward right as shown. Space is gravity free. Choose the correct options :
Figure \( 1.430 \)
(A) Net force from the hinge on the rod is zero
(B) Net force from the hinge on the rod is left wards
(C) Equilibrium of rod is neutral
(D) Equilibrium of rod is stable
