MHT CET 2026 Physics question
A Pipe open at one end has length 0.8m. At the open end of the tube a string 0.5m long is vibrating in its first overtone and resonates with fundamental frequency of pipe. If tension in the string is 50 N, the mass of string is (Neglect end correction) (Speed of sound=320m/s)
Answer: (C)
Solution
Pipe closed at one end (open at the other): fundamental . The string vibrates in its first overtone, i.e. the second harmonic: . Resonance gives ,
