Answer:

Linear mass density,
\lambda=2* 10^(-4)\ kg/m

Step-by-step explanation:

Given that,

Mass of the string, m = 0.3 g = 0.0003 kg

Length of the string, l = 1.5 m

The linear mass density of a string is defined as the mass of the string per unit length. Mathematically, it is given by :


\lambda=(m)/(l)


\lambda=(0.0003\ kg)/(1.5\ m)


\lambda=0.0002\ kg/m

or


\lambda=2* 10^(-4)\ kg/m

So, the linear mass density of a string is
2* 10^(-4)\ kg/m. Hence, this is the required solution.
