Homework Equations
First of all I have a doubt.So equations are out of question. At least I know that it is a question...
Yes thank you , I got the solution.Here it is as follows:
From the first equation we get $$t_1=\frac{2u_1-2u}{f-f_1}$$
Now substituting the value of L in the second equation we get the desired result..
