In a system, unit of mass is \(A \mathrm{~kg}\), length is \(B \mathrm{~m}\) and time is \(C\) s, then the value of \(10 \mathrm{~N}\) in this system is
B We know that, \(\mathrm{N}_{1} \mathrm{u}_{1}=\mathrm{N}_{2} \mathrm{u}_{2}\) \(\Rightarrow \quad 10 \mathrm{~kg} \frac{\mathrm{m}}{\mathrm{s}^{2}}=\mathrm{N}_{2}\left(\frac{\mathrm{A} \cdot \mathrm{B}}{\mathrm{C}^{2}}\right)\) \(\Rightarrow \quad \mathrm{N}_{2}=\frac{10 \cdot \mathrm{C}^{2}}{\mathrm{~A} \cdot \mathrm{B}}\) \(=10 \mathrm{~A}^{-1} \mathrm{~B}^{-1} \mathrm{C}^{2}\) So, numerical value of \(10 \mathrm{~N}\) in given system is \(10 \mathrm{~A}^{-1} \mathrm{~B}^{-1} \mathrm{C}^{2}\).
