in a resonance tube experiment using a closed tube the smallest value of l for which a peak in sound intensity occurs in 9 cm how much the tube must be raised to hear the next peak in intensity ignore the end correction​

explanation:

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

force required to detach it is given by

charges are taken to be fundamental charge

now we have

so above is the minimum distance at which it will detach
