C is the answer. If 10 men were to pull on a tree, the tree would be exerting an equal but opposite force, taking on the exact roll of the 10 men on the other side in choice a.
ReplyDeleteanswer is "c". The rope breaking has to do with tensile strength so it does not matter from where the force comes from but that you exceed the force capable of the object.
