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 M, the wire resonates with the same tuning fork forming three antinodes for the same positions of the bridges. The value of M is
- 25 kg
- 5 kg
- 12.5 kg
- (1/25) kg.
Answer
(D) (1/25) kg.
