  • question_answer
    In an electroplating experiment \[m\,\,g\]of silver is deposited, when 4 amperes of current flows for 2 minutes. The amount (in \[gms\]) of silver deposited by 6 amperes of current flowing for 40 seconds will be [MNR 1991]

    A)                 \[4m\] 

    B)                 \[m/2\]

    C)                 \[m/4\]

    D)                 \[2m\]

    Correct Answer: B

    Solution :

               \[m=Z\times 4\times 120\] ; \[M=Z\times 6\times 40\]                                 \[\frac{M}{m}=\frac{6\times 40}{4\times 120}=\frac{1}{2};\,\,\,\,\,M=m/2\].
