    A boy of \[50\,\,kg\] is standing in a lift moving down with an acceleration\[9.8\,\,m/{{s}^{2}}\]. The apparent weight of the boy will be

    A) \[50/9.8\,\,N\]                 

    B) \[50\times 9.8\,\,N\]

    C) \[50\,\,N\]                         

    D) \[zero\]

    Correct Answer: D

    Solution :

    Mass of the boy\[m=50\,\,kg\] Downwards acceleration of lift\[a=9.8\,\,m/{{s}^{2}}\] Apparent weight of the boy when the lift is moving downwards is given by \[W=m(g-a)=50(9.8-9.8)=0\]
