A steel wire of length 60 cm and area of cross section `10^(-6)m^(2)` is joined with a n aluminimum wire of length 45 cm and are of cross section `3xx10^(-6)m^(2)`. The composite string is stretched by a tension of 80 N. Density of steel is `7800kgm^(-3)` and that of aluminimum is `2600kgm^(-3)` the minimum frequency of tuning fork. Which can produce standing wave in it with node at joint is
