Homework Help: How do you calculate tension in the string?

    1. The problem statement, all variables and given/known data

    A guitar string with a linear density of 2.0 g/m is stretched between supports that are 60 cm apart. The string is observed to form a standing wave with three antinodes when driven at a frequency of 420 Hz.

    What is the tension in the string?

    I don't have any formulas to even begin solving the problem. i just know f= v/x an f= 1/period? My book does not have any formulas pertaining to tension and the teacher never taught us this information.
