A violin string has a length of 0.350m and is tuned to concertG, with fg=392 Hz. Where must the violinst place her finger to playconcert A, with fa=440 Hz? If this position is to remain correct toone-half the width of a finger (that is, to within 0.600 cm), what is the maximum allowable percentage change in the stringtension?
