Alright, lets get started.
the tension in the string in the vertical case (tv)
the tension in the string in the horizontal case (th)
Given that the tension in the string in the vertical case (tv) is 15% larger than the tension in the string in the horizontal case (th).
So, the expression will be :
[tex]tv = th + th*\frac{15}{100}[/tex]
[tex]tv = th + 0.15 th[/tex]
[tex](tv) = 1.15 (th)[/tex] : Answer
Hope it will help :)
