Two identical weightless pulleys are mounted with parallel axes at the same height. A non-elastic weightless rope is passed through both pulleys with identical weights on the ends (fig.)
The system is in equilibrium. One of the weights is pulled to one side and released. Is equilibrium broken?
Text Solution
Verified by ExpertsThe correct answer is:
A
Step 1: In the initial position, the system is in equilibrium with two weights balanced on either side of the pulleys.
Step 2: When one weight is pulled to one side, it creates an imbalance in the forces acting on the system. The tension in the rope is no longer equal to the weight on the other side.
Step 3: Consequently, the side with the pulled weight becomes heavier and will descend, further breaking the equilibrium.
Therefore, equilibrium is indeed broken when one weight is pulled to one side and released.
