Physics - NLM Question with Solution | TestHub
In order to test the strength of a rope, one end is tied to a large tree and the other end is hitched to a team of 2 horses. The horse pull as hard as they can, but cannot break the rope. If the rope is untied from the tree and attached to another team of 2 horses with equal strength, and the two teams pull in opposite directions, the tension in the rope will
Options:
Answer:
Solution:
When the rope is tied to the tree, the tree pulls the rope back with exactly the same force that the team of horses applies (the rope is in equilibrium). The tension in the rope equals the pull of one team.
Replacing the tree by a second team of 2 horses pulling the other way changes nothing: each team plays the role the tree played, pulling with the same force, and the tension in the rope is the same as before.
(The tension is NOT doubled - the two teams do not add; each team's pull is the reaction to the other's.)
Correct option: (B).
