Question

A body of weight \( W \) is suspended from the ceiling of a room through a chain of weight \( w \). The ceiling pulls the chain by a force.

• A. \( w \)
• B. \( {Wg} \)
• C. \( \dfrac{w + W}{2g} \)
• D. \( \dfrac{w - W}{2} \)
• E. \( w + W \)

Hint:

In problems related to forces and weight, always remember that the total force is the sum of all the forces acting on the object.

Answer 1

Answer: (E)

In the given problem, the force exerted by the ceiling on the chain is equal to the sum of the weights of the body and the chain, which is: \[ F = W + w \] Hence, the correct answer is (E).
