Consider the case where m1 and m2 are both non-zero, and m2> m1. let t1 be the magnitude of the tension in the rope connected to the block of mass m1, and let t2 be the magnitude of the tension in the rope connected to the block of mass m2. which of the following statements is true?
(a)-t1 is always equal to t2.
(b)-t2 is greater than t1 by an amount independent of velocity.
(c)-t2 is greater than t1 but the difference decreases as the blocks increase in velocity.
(d)-there is not enough information to determine the relationship between t1 and t2.
