Tension in an Accelerated System

    1. The problem statement, all variables and given/known data

    3. The attempt at a solution

    "Any objects attached to the rope will have the same magnitude of acceleration as the rope." So since no mass is given, I assumed all the masses are the same. So wouldn't A be the answer?

    The tension FT3 only has to accelerate the third mass upwards. FT2 has to accelerate both the second and third mass. FT1 has to... you get the picture. So the tensions are not equal.
