354871 A string of length \(l\) hangs from the rigid support \(B\). The linear mass density of the string \(\mu=\mu_{0}\left(\dfrac{x}{l}\right)\). Choose incorrect option from following.
supporting img

1 Tension at \(P\) is \(\dfrac{\mu_{0} g x^{2}}{2 l}\)
2 Acceleration of the wave pulse at \(P\) is \(\dfrac{g}{4}\)
3 Time taken by the pulse to move from \(A\) to \(B\) is \(2 \sqrt{\dfrac{l}{g}}\)
4 The distance covered by the wave pulse during the time in which pulse reaches to \(B\) from \(A\) is \(3 l\), if \(B\) is accelerating upwards with \(g\)

354873 A uniform rope length \(L\) and mass \(m_{1}\) hangs vertically from a rigid support. a block of mass \(m_{2}\) is attached to the free end of the rope. A transverse pulse of wavelength \(\lambda_{1}\) is produced at the lower end of the rope. The wavelength of the pulse when its reaches the top of the rope is \(\lambda_{2}\). the ratio \(\lambda_{2} / \lambda_{1}\) is.

1 \(\sqrt{\dfrac{m_{1}}{m_{2}}}\)
2 \(\sqrt{\dfrac{m_{1}+m_{2}}{m_{2}}}\)
3 \(\sqrt{\dfrac{m_{2}}{m_{1}}}\)
4 \(\sqrt{\dfrac{m_{1}+m_{2}}{m_{1}}}\)
