A) \[gx\]
B) \[\sqrt{gx}\]
C) \[gL\]
D) \[\sqrt{gL}\]
Correct Answer: B
Solution :
Total length of string = L Mass of the string = M The velocity of transvers wave \[v=\sqrt{\frac{T}{m}}\] where,\[T=\] weight of part of string hanging below the point under consideration \[=\left( \frac{M}{L1} \right)xg\] \[\Rightarrow \] \[v=\sqrt{\frac{\left( \frac{M}{L} \right)xg}{\left( \frac{M}{L} \right)}}=\sqrt{xg}\]You need to login to perform this action.
