Answer :
Answer:
Linear mass density,[tex]\lambda=2\times 10^{-4}\ kg/m[/tex]
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 :
[tex]\lambda=\dfrac{m}{l}[/tex]
[tex]\lambda=\dfrac{0.0003\ kg}{1.5\ m}[/tex]
[tex]\lambda=0.0002\ kg/m[/tex]
or
[tex]\lambda=2\times 10^{-4}\ kg/m[/tex]
So, the linear mass density of a string is [tex]2\times 10^{-4}\ kg/m[/tex]. Hence, this is the required solution.
