MHT CET 2026 Physics question
Two uniform wires of same material are vibrating under the same tension. If the first overtone of the first wire is equal to the second overtone of the second wire and radius of first wire is twice the radius of second wire then the ratio of length of first to second wire is
Answer: (B)
Solution
For a stretched wire the -th harmonic is , with . The first overtone is the 2nd harmonic and the second overtone is the 3rd harmonic. So and $ =
