Question

a mass w1 attached to a string of weight w2 from ceiling what force

Answer 1

Hi..

Since the action reaction force is in equlibrum so action reaction force will be equal .The ceiling pulls the chain with a force equal to the sum of weights of chain and the body.So the pulling force = (w1 + w2)

Hope this helps u!

Answer 2

The force is mass ×a. Therefore 10m/S2 × w1+w2
