A heavy string is tied at one end to a movable support and to a light thread at the other end as shown in figure-6.113. The thread goes over a fixed pulley and supports a weight to produce a tension. The lowest frequency with which the heavy string resonates is \( 120 \mathrm{~Hz} \). If the movable support is pushed to the right by \( 10 \mathrm{~cm} \) so that the joint is placed on the pulley, what will be the minimum frequency at which the heavy string can resonate ?
