Question

A body of weight w₁ is suspended from the ceiling of a room by a chain of weight w₂. The ceiling pulls the chain by a force.

Options

•  w₁

• w₂

• w₁ + w₂

• \[\frac{w_1 + w_2}{2}\]

Answer 1

w₁ + w₂


From the free-body diagram,
(w₁ + w₂) – N = 0
N = w₁ + w_{2
The ceiling pulls the chain by a force (w1 + w2).}
