Problem

A sonometer wire resonates with a given tuning fork forming standing waves with five antinodes between the two bridges when a mass of 9 kg is suspended from the wire. When this mass is replaced by a mass MM, the wire resonates with the same tuning fork forming three antinodes for the same positions of the bridges. The value of MM is [2002S] (1) 25 kg (2) 5 kg (3) 12.5 kg (4) 1/25 kg
