Three charges (each \( Q \) ) are placed at the three corners of an equilateral triangle. A fourth charge \( q \) is placed at the center of the triangle. The ratio \( |q / Q| \) so as to make the system in equilibrium is
(1) \( 1: 3 \)
(2) \( 1: \sqrt{3} \)
(3) \( \sqrt{3}: 1 \)
(4) \( 2: \sqrt{3} \)
