Question

a 10 KG wire has cross sectional area 10 cm square and length 10 M what is the numerical value of linear mass density of the wire?

Answer 1

Hello Dear.

Here is the answer---


→→→→→→→→→→

Given---

Mass of the Wire = 10 kg.
Length of the Wire = 10 m

Using the Formula,

     Linear Mass Density of the Wire(λ) = Mass/Length
                                                                = 10/10
                                                                = 1 kg/m

Thus, the linear mass Density(λ)  of the Wire is 1 kg/m.

Answer 2

Hey mate !!

Here's the answer !!

Given :-

1. Mass = 10 kg

2. Length = 10 m 

3. Area of cross-section = 10 cm²

To find :-

Linear mass density of the wire.

Proof :-

We know that,

Linear mass density = Mass / length

Mass = 10 kg , Length = 10 m

Linear mass density = 10 kg / 10 m

=> 1 kg / m

Hence Linear mass density = 1 Kg per metre.

Hope my answer helped you !!

Cheers !!

Have a good day :-)
