A tuning fork of frequency 256 produces 4 beats per second with another tuning fork B. When the prongs of B are loaded with 1 gm wt, the number of beats is 1 per second and when loaded with 2 gm wt, the number of beats becomes 2 per second. What is the frequency of B?

A vibrating string of certain length l under a tension T resonates with a mode corresponding to the first overtone (third harmonic) of an air column of length 75cm inside a tube closed at one end. The string also generates 4 beats per second when excited along with a tuning fork of frequency n . Now when the tension of the string is slightly increased the number of beats reduces 2 per second. Assuming the velocity of sound in air to be 340 m//s , the frequency n of the tuning fork in Hz is
