state gov BSSC Laboratory Assistant Mock Test Series 2025 Physics Waves Wave Speed on a Stretched String
A string of length \(L\) and mass \(M\) hangs freely from a fixed point. Then the velocity of transverse waves along the string at a distance \(x\) from the free end is
1
\(\sqrt{gL}\)
2
\(\sqrt{gx}\)
3
\(gL\)
4
\(gx\)
