- 15. Multiple Choice
Find the tension on a rope tied to a tree branch and a 2 kg swing with a 35 kg girl sitting on it.
Was the tension higher near the tree branch or near the swing?
52.35 N
The tension is highest near the tree branch.
37 N
The tension is the same throughout the rope's length.
370 N
The tension is the same throughout the rope's length.
370 N
The tension is highest near the swing because that is where she is sitting.
