An iron load of 2 {\kg} is suspended in air from the free end of a sonometer wire of length 1 {\m}. A tuning fork of frequency 256 {\Hz}, is in resonance with {1}/{\sqrt{7}} times the length of the sonometer wire. If the load is immensed in water, the length of the wire in metre that will be in resonance with the same tuning fork is (Specific gravity of iron =8 )
