Question

A string of length `L` fixed at its at its both ends is vibrating in its `1^(st)` overtone mode. Consider two elements of the string of same small length at position `l_1=0.2L` and `l_2=0.45L` from one end. If `K_1` and `K_2` are their respective maximum kinetic energies then
A. `K_(1) = K_(2)`
B. `K_(1)gt K_(2)`
C. `K_(1)lt K_(2)`
D. it is not possible to decide the relation.

Answer 1

Correct Answer - B
A string of …………..
It is obvious that particle at `0.2 L` will have large amplitude that particle at `0.45 L, 0.5 L` being the node asnd `0.25` being the node and `0.25` being antinode.
