With the information provided, there is an implication that we are looking at a scenario where a rope is subjected to forces and we wish to determine what force would cause it to stop moving.
We need to consider the concept of equilibrium, where the net force on an object is zero, allowing the object to either remain at rest or move at a constant velocity (according to Newton's first law of motion). The picture appears to describe a system where two pairs of forces are being applied to the rope.
If we have a 100 N force being applied to the right at both ends, the net force on the rope would be zero because they are equal and opposite, so the rope would not begin moving or, if it was already moving, it would continue moving at a constant velocity.
If we want the rope to stop moving, we need to apply a force equal in magnitude and opposite in direction to the current net force acting on the rope. Without specific details on whether the rope is already moving and in which direction, it's not possible to definitively say which option is correct.
Suppose the rope is moving to the left due to a previously applied force. In that case, to stop it, we would need to apply a force to the right that balances out any existing net force.
However, if the rope is not moving and is currently in equilibrium with 100 N forces pulling to the right on both ends, then any of the other forces (100 N to the left, 300 N to the left, or 400 N to the right) would cause the rope to move in the direction of the net force resulting from the combination of forces, rather than to stop moving.
In summary, if the rope is already at equilibrium (not moving or moving at a constant velocity), any additional force would cause it to start moving or change its velocity, not stop. To stop a moving rope, we would have to apply a force equal to the net force already acting on the rope but in the opposite direction. Without additional context or a clear indication of the current motion or forces involved, it's impossible to answer definitively which force would cause the rope to stop moving.
