• # question_answer A block of mass ${{m}_{1}}$is suspended from the ceiling of a room through a rope of mass${{m}_{2}}.$ The ceiling pulls the chain by a force A) ${{m}_{1}}g$                                  B) $({{m}_{1}}+{{m}_{2}})g$         C)      $\frac{({{m}_{1}}{{m}_{2}})g}{2}$         D)      ${{m}_{2}}g$

Correct Answer: B

Solution :

Let the sought force be F. For the equilibrium of the entire system $F={{m}_{1}}g+{{m}_{2}}g=({{m}_{1}}+{{m}_{2}})g$ Hence, the correction option is (b).
