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. The musician increases the tension in the guitar string and notices that the beat frequency increases. Choose the correct answer from the options below. Find the original frequency of this note fG in Hz on the guitar string. Determine the ratio T ' / T between the tension in the guitar string before tuning T and the tension in the guitar string once it is tuned T ' to eliminate the beat frequency.
