Question

Consider a string with 36.2 g mass and 39.6 cm length. Determine the linear density of the string (in kg/m unit).

Answer 1

Answer:

Linear density  will be 0.0914 kg/m      

Explanation:

We have given mass of the string m = 36.2 kg

Length of the string L = 39.6 cm

We know that 1 kg = 1000 gram

So 36.2 gram $=\frac{36.2}{1000}=0.0362kg$

Also we know that 1 meter = 100 cm

So 39.6 cm $=\frac{39.6}{100}=0.396m$

We have to calculate the linear density

Linear density is given by $linear\ density=\frac{mass}{length}=\frac{0.0362}{0.396}=0.0914kg/m$
