Did I Get The Correct Answer?

A piano uses vibrating strings to produce musical notes. Suppose a piano tuner finds that the note corresponding to 440 Hz is slightly off. The string has a linear mass density of 2 g/m, and has a length of 65 cm. What should the tension in the string be to produce the correct note?

I used f=½L x sqrt(T/mew)
I got 654.37 N
Did I use the correct equation and get the correct answer?

Yup. You've used Mersenne's equation correctly and come up with the right answer. (Well, it's the same one as I got anyway!).
