Tylor has a tuning fork that resonates at 330 Hz and a 3 m string (mass is not known), held at both ends. He puts the fork close to the string to excite it. He controls the string tension, a force measurer shows the amount of force . He looks at the successive resonances of the string in response to the tuning fork when the tension is 140N and 800N. Please calculate the string mass? There might be a 0.49N uncertainty with the force measurer
