Answer to Question #79041 in Electricity and Magnetism for Mili

Question

A wire with an alternating current flowing through it is placed in a magnetic field . This causes the wirw to oscillate with a frequency equal to the frequency of the current . This wire has a length L= 1.56 m . A mass of 221.0 g is hung on the end of the wire . The frequency of the current is initially set to f =52.5 hz . Three loops are observed in the wire at this frequency . 1. What is the wave velocity of the travelling wave ?
2. What is the mass per unit length for this wire?
3. What is the wavelength of the fundamental mode of vibration of the wire ?
