Question

To apply Problem-Solving Strategy 12.1 Standing waves and normal modes.

A cellist tunes the C string of her instrument to a fundamental frequency of 65.4 Hz . The vibrating portion of the string is 0.600 m long and has a mass of 14.4 g .

1. With what tension must she stretch that portion of the string?
2. What percentage increase in tension is needed to increase the frequency from 65.4 Hz to 73.4 Hz , corresponding to a rise in pitch from C to D?

I cant figure out part G.

Part G

If you were to tune the same string to a lower fundamental frequency of 55.0 Hz , what tension FT would be required in the string?

Express your answer in newtons.
