Physics - NLM Question with Solution | TestHub

Consider the arrangement shown in given figure ${\mathrm{m}}_1=7.5\mathrm{kg},{\mathrm{m}}_2=10\mathrm{kg}$and mass per unit length of the string is $15\times 10^{-3}\mathrm{kg}/\mathrm{m}$. At $\mathrm{t}=0$, the system is released from rest and at the same instant of time a transverse pulse is produced at A. The pulley B is at a distance $=10\mathrm{m}$from A at $\mathrm{t}=0$. Assuming all surface to be frictionless and all pulleys to be massless. If the time taken by the pulse to reach to the pulley B is t sec, then write 10 t in OMR sheet.
