MHT CET 2022 Physics question

A string is vibrating in its fifth overtone between two rigid supports 2.4 m apart. The distance between successive node and antinode is

(A)0.8 m
(B)0.2 mCorrect
(C)0.1 m
(D)0.6 m

Answer: (B)

Solution

For a string fixed at both ends, the fifth overtone is the sixth harmonic, so it has 6 loops: . Hence m. The distance between a successive node and antinode is
