In the figure shown ABC is a uniform wire. If centre of mass of wire lies vertically below point A, then `(BC)/(AB)` is close to :

In the figure shown AB, BC and PQ are thin, smooth, rigid wires. AB and AC are joined at A and fixed in vertical plane. angleBAC = 2theta = 90^(@) and line AD is angle bisector of angle BAC. A liquid of surface tension T = 0.025 N/m forms a thin film in the triangle formed by intersection of the wires AB, AC and PQ. In the figure shown the uniform wire PQ of mass 1 gm is horizontal and in equilibrium under the action of surface tension and gravitational force. Find the time period of SHM of PQ in vertical plane for small displacement from its mean position, in the form (pi)/X s and fill value of X.
