The length of the wire between two ends of a sonometer is 100 cm. What should be the positions of two bridges below the wire so that the three segments of the wire have their fundamental frequencies in the ratio 1 : 3 : 5.
${{1500} \over {23}}cm,{{500} \over {23}}cm$
${{1500} \over {23}}cm,$ ${{300} \over {23}}cm$
${{300} \over {23}}cm,{{1500} \over {23}}cm$
${{1500} \over {23}}cm,{{2000} \over {23}}cm$
