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
