    Two masses \[{{M}_{A}}\] and\[{{M}_{B}}\]\[({{M}_{A}}<{{M}_{B}})\] are weighed using same weighing machine. In the measured value

    A)  Absolute error is same for both, relative error is greater for \[{{\text{M}}_{\text{A}}}\]and lesser for \[{{\text{M}}_{\text{B}}}\].

    B)  Absolute error is same for both, relative error is greater for \[{{\text{M}}_{\text{B}}}\] and lesser for \[{{\text{M}}_{\text{A}}}\].

    C)  Relative error is same for both, absolute error is greater for \[{{\text{M}}_{\text{A}}}\]and lesser for \[{{\text{M}}_{\text{B}}}\].

    D)  Relative error is same for both, absolute error is greater for \[{{\text{M}}_{\text{B}}}\] and lesser for \[{{\text{M}}_{\text{A}}}\].

    Correct Answer: A

    Solution :

     Relative error (for\[{{\text{M}}_{\text{A}}}\])\[\text{=}\frac{\text{Absolute}\,\text{error}}{{{\text{M}}_{\text{A}}}}\]
