Two strings with linear densities of 5 g/m are stretched overpulleys, adjusted to have vibrating lengths of 50 cm, and attached to hanging blocks. Theblock attached to string 1 has a mass of 20 kg and the block attached to string 2 has massM. Listeners hear a beat frequency of 2 Hz when string 1 is excited at its fundamentalfrequency and string 2 is at its third harmonic.
Required:
What is one possible value for mass M?
