MHT CET 2022 Physics question
A uniform wire of length 'L', diameter 'D' and density '' is stretched by a tension 'T'. The correct relation between its fundamental frequency of vibration 'f', the length 'L' and the diameter 'D' is
Answer: (B)
Solution
The fundamental frequency of a stretched wire is , where is the mass per unit length. . So \frac{1}{2L}$ =
