Question
If an addition of 1250 g tension of string raises its pitch to interval fifth, what is the original tension?
Solution
Interval fifth corresponds to the frequency ratio 3:2.
Let T be the original tension in the string.
Relation between velocity and tension is given by,
∴
i.e.,
, is the original tension of the string.
