2 of 3Cart C is connected to hanging masses A and B by means of ropes and pulleys as shown. A is heavier than B. After being released into motion from rest, the tension in A’s rope will
1. Remain greater than that in B’s rope.2. Become equal to that in B’s rope.3. Become less than that in B’s rope.
