A chain composed of four identical links is suspended by a rope and does not move. What are the forces on each chain? (include where they come from)

how the electric force between tow positive charges changes under the distance between the charges in tripled

Wha?

To determine the forces acting on each chain link, we need to consider the forces in equilibrium. In this scenario, the chain is hanging motionless, implying there is a balance of forces acting on each link.

Let's break down the forces acting on each chain link:

1. Tension Force (T): The tension force is the force exerted by the rope, holding the chain. Since the chain is not moving, the tension force acting upwards is equal to the weight of the chain acting downwards.

2. Weight (W): The weight of each chain link contributes to the force acting downward. In this case, the weight is the force of gravity acting on each link. Considering that all four chain links are identical, the weight is evenly distributed among them.

Therefore, each chain link experiences an equal and opposite force pair:

- The tension force (T) acting upwards, exerted by the rope.
- The weight force (W) acting downward, due to the force of gravity.

In summary, each chain link experiences tension force acting upwards and weight force acting downwards, exerted respectively by the rope and gravity.
