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

Linear density will be 0.0914 kg/m

Step-by-step 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
`=(36.2)/(1000)=0.0362kg`

Also we know that 1 meter = 100 cm

So 39.6 cm
`=(39.6)/(100)=0.396m`

We have to calculate the linear density

Linear density is given by
`linear\ density=(mass)/(length)=(0.0362)/(0.396)=0.0914kg/m`
