A transverse wave is set up on a string of mass 2.00 g and length 70.0 cm. The speed of the wave is 200 m/s. The string was kept under tension by hanging an object of mass m at the one end of the string. What is the mass of this object?
The mass of the object = kg
The linear mass density of the string is
From the speed of the wave
we can calculate the tension t
From the tension
we can calculate the mass of the hanging object
