Question

1. two groups of students are playing a game of tug - of - war. one group is pulling the rope to the left and the other group is pulling the rope to the right. if neither group has moved from its starting position, what has to be true? the two groups are pulling on the rope with equal force in opposite directions. the two groups are pulling on the rope with unequal force in opposite directions. the two groups are pulling on the rope with equal force in the same direction. the two groups are pulling on the rope with unequal force in the same direction.

Explanation:

Step1: Recall Newton's first - law

An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. In a tug - of - war, if the rope does not move, the net force on the rope is zero.

Step2: Analyze the forces

The two groups are pulling on the rope. For the rope to remain stationary, the forces exerted by the two groups must be equal in magnitude and opposite in direction. This is in accordance with Newton's third law (action - reaction forces) and the condition for equilibrium (net force = 0).

Answer:

The two groups are pulling on the rope with equal force in opposite directions.
