Question

The system to be studied is shown in the figure; a horizontal string passes over a pulley, and a mass hangs vertically from the string. If the mass is at rest and the mass of the pulley can be neglected, find the tension in the string. Record this as Equation 2 in your Lab Notebook for Experiment 12. If the vibrator is turned on, a wave will travel along the string. Write down the equation for the velocity of a wave in terms of the wave's wavelength and frequency. Record this as Equation 4 in your Lab Notebook for Experiment 12.

Explanation / Answer

1.T=mg

2.v=sqrt(T/mu)=sqrt(mg/mu)

where mu = linear mass density
