Question

If velocity, time and force were chosen as basic quantities the dimensions of mass will be

• A. $\left[FT{V}^{-1}\right]$
• B. $\left[F^{-1}TV\right]$
• C. $\left[F{T}^{-1}V\right]$
• D. $\left[F^{-1}{T}^{-1}V\right]$

Answer 1

The correct option is A $\left[FT{V}^{-1}\right]$

Velocity, time, force and mass are related by:
$Momentum=Force\times time$
$m\times v=Force\times time$
$m=Force\times time\times v^{-1}=FT{V}^{-1}$
