\((\because \text { end correction } \mathrm{e}=1 \mathrm{cm} \text { given })\)
For second resonance, \(\frac{3 \lambda}{4}=\ell_{2}+\mathrm{e}\)
\(\Rightarrow \ell_{2}=3 \times 11-1=32 \mathrm{cm}\)
$y=\left(10 \cos \pi x \sin \frac{2 \pi t }{ T }\right) cm$
$x=\frac{4}{3} cm$ આગળ રહેલા કણનો કંપવિસ્તાર.....$cm$ હશે
