If the unit of force is

\mathrm{kN}

, the length is

1 \mathrm{~km}

and time

100 \mathrm{~s}

, then what will be the unit of mass?

View answer and explanation

Correct option: C

10000 \mathrm{~kg}

Option C (

10000 \mathrm{~kg}

) is correct because force = mass * acceleration, so mass = force / acceleration. Converting the units, we get mass = (1000 N) / (1000 m / (100 s)²) = 10000 kg.
