A string of length 50 cm and mass 2 5 g is fixed at both ends A pipe closed at one end has a length of 85 cm When the string vibrates in its second overtone and the air column in the pipe in its first overtone they produce a beats frequency of 6 Hz It is also observed that decreasing the tension in the string decreases beats frequency Neglect the end correction in the pipe and velocity of sound in air is 340 m s then the tension in the string is A 72 N C 26 N B 52 N D 18 N
