The problem statement is illegible. It is good form in these forums to present the problem in text form and use images for supporting drawings and such. Similarly, it is good form to put your answer in text form rather than in scribbles. Superscripts, subscripts and special symbols (the ∑ icon above the editting pane) are available to make the text form prettier. You can even use TeX to typeset your equations, e.g. ##F=\rho g v##

Your answers to a and b look fine, but I cannot follow your working in c. When you post a typed version of that, please explain your reasoning.

well c is my problem to me. should i take account the length difference only or is there sth more?

Ok, but I cannot decipher your working. Please repost as typed equations, with some explanation of your reasoning.
 
Yes, please repost as typed equations.
