A musician uses a tuning fork of frequency f = 243 Hz to tune his guitar and his trumpet. There is a beat frequency between the tuning fork and the guitar string and between the tuning fork and the trumpet for this note of fbeat = 5 Hz. If the original tension T is 100 N, what must be the new tension T ' in Newtons? The musician increases the length of an air column in the trumpet and notices that the beat frequency increases. Choose the correct answer from the options below. Find the original frequency of this note fT in Hz from the trumpet.
