Could anyone explain to me how to solve problem number three of this worksheet? Does the tension vestor change if the vertical ropes have different lenghts?

No, the tension vector will be the same for both ropes.
The tension vector just shows how much force is applied to it.
A 10 cm string holding a 20 newton weight would have 20 newtons of tension.
A 5 cm string holding a 20 newton weight would also have 20 newtons of tension.

Since they are vertical, each have the same tension. It doesn't matter about unequal lengths, other than it would be terrible trying to swing on those rings!
