The Martians use force $(F)$, acceleration $(A)$ and time $(T)$ as their fundamental physical quantities. The dimensions of length on Martians system are
$F{T^2}$
${F^{ - 1}}{T^2}$
${F^{ - 1}}{A^2}{T^{ - 1}}$
$A{T^2}$
The dimensions of electric potential are
A force is represented by $\mathrm{F}=a \mathrm{x}^2+\mathrm{bt}^{1 / 2}$. Where $\mathrm{x}=$ distance and $\mathrm{t}=$ time. The dimensions of $\mathrm{b}^2 / \mathrm{a}$ are :
Dimensional formula for pressure head is ............
The fundamental unit which has the same power in the dimension formula of surface tension and viscosity is
If momentum $(P)$, area $(A)$ and time $(T)$ are taken to be fundamental quantities then energy has dimensional formula
