Ahorizontal string is attached at one end to an electrical vibrator of frequency 50.0 hz, and at the other to a set of hanging masses. the string has a mass per unit length 0.115 gm^-1. when the string has a length 210.4 cm five loops are observed. what mass (in grams) is hung from the string? you adjust the frequency so that you now observe 4 loops on the string leaving the hanging mass and string length the same. what is the new frequency?
