Thanks​

? It is simply using the definition of "proportional".

 

[Nanas]

This is not my problem

My Problem and question why I we use the inverse square proportional .

 

[atyy]

From Eq 22, A is unitless.

From Eq 36, C/A must have units of 1/vx so that A on the LHS is unitless.

So if C/A is proportional to vx, the constant of proportionality is chosen to have units of 1/v². The constant of proportionality is written as 1/V² to make this clear.

Thank you.

I understanded it now.
