A tuning fork of frequency 512 Hz is vibrated with a sonometer wire and 6 beats per second are heard. The beat frequency reduces if the tension in the string is slightly increased. The original frequency of vibration of the string is

A transverse periodic wave on a string with a mass density of 0.200 kg/m is described by the following equation y=0.05sin(420t−21.0x) where x and y are in meters and t is in seconds. Tension in the string is
