When tension 'T' is applied to a sonometer wire of length 'l', it vibrates with fundamental frequency 'n'. Keeping the experimental setup same, when the tension is increased by 8 newton, the fundamental frequency becomes three time the earlier fundamental frequency (n). The initial tension applied to the wire in newton, was [MHT-CET 2023]

Answer: (C)

Solution

: , so and N; 2.5, 0.5 and 2.0 do not satisfy this. Hence the correct option is (c).
