  • question_answer
    If force (F), length (L) and time (T) be considered fundamental units, then units of mass will be

    A)                                        \[\left[ \text{F}{{\text{L}}^{-\text{1}}}{{\text{T}}^{\text{2}}} \right]\]                

    B)                                              \[\left[ {{\text{F}}^{2}}\text{L}{{\text{T}}^{\text{-2}}} \right]\]

    C)                                                                     \[-\text{273}.\text{15}{}^\circ \text{F}\]      

    D)                                                                     \[-\text{453}.\text{15}{}^\circ \text{F}\]

    Correct Answer: C

    Solution :

                    Let                                                        \[\text{52}00\text{{ }\!\!\mathrm{\AA}\!\!\text{ }}\]                                                                             \[\text{Vc}=\text{1}.\text{5V}\] On comparing both sides                                                                           \[\text{1}00\text{ }\mu \text{A}\]                                                                           \[\text{15}0\text{ }\mu \text{A}\]                                                                                              \[\text{5 mA}\]                                                                                             \[\text{10 mA}\] Units of mass is                                                                              \[\text{ }\!\!\beta\!\!\text{ }\]
