Question
T1 > T2, because the first rope attached must hold the full weight of the loudspeaker before the second rope is attached.
T1 > T2, because rope 1 is shorter than rope 2.
T1 = T2, because two ropes attached to the same loudspeaker should have the same tension.
T1 = T2, because the ropes attach to the loudspeaker at the same point and at the same angle.

Correct
This is a type of reasoning, used often in physics, called a symmetry argument. Since the ropes are in identical situations, except for one being the
mirror image of the other, they have to possess identical tensions. Since the two tensions have equal magnitude, just use T to denote the magnitude
of the tension in either rope. With the information you have gathered here, you can build the visual overview:
