Why the Find function doesn't work?

I'm trying to solve for f in an equation. All the variables in that equation are previously defined. but I can get the find function to work. this is very confusing. Can somebody let me know what is wrong with my work please? thanks !

You need to provide an initial guess for f.  Put this just before the Given keyword.  You could use f := 1N here for example.

However, in this instance the use of Find is unnecessary; just divide the LHS by -L.

Hi,

 

You can use the root function.
