हिन्दीIf the unit of force is \( 100 \text{ N} \), the unit of length is \( 10 \text{ m} \), and the unit of time is \( 100 \text{ s} \), then the unit of mass in this system is:
View Answer & Solution
Correct answer · Option B
\( 10^4 \text{ kg} \)
Explanation
Force \( F = MLT^{-2} \implies M = \frac{F T^2}{L} \). Substituting units: \( M' = \frac{100 \times (100)^2}{10} = \frac{10^6}{10} = 10^5 \text{ g} = 10^4 \text{ kg} \).
