Answer:
linear density of the string = 4.46 × 10⁻⁴ kg/m
Explanation:
given,
mass of the string = 31.2 g
length of string = 0.7 m
linear density of the string = [tex]\dfrac{mass\ of\ string}{length}[/tex]
linear density of the string = [tex]\dfrac{31.2\times 10^{-3}\ kg}{0.7\ m}[/tex]
linear density of the string = 44.57 × 10⁻³ kg/m
linear density of the string = 4.46 × 10⁻⁴ kg/m
