Tension is maintained in a string by attaching one end to a wall and by hanging a 2.34 kg object from the other end of the string after it passes over a pulley that is 2.00 m from the wall. The string has a mass per unit length of 3.45 mg/m. What is the fundamental frequency of this string?
Please help. do I use f=1/2L sqrt(tension/wavelenght)? Thank you.
