Question

The Martians use force (F) , acceleration (A) and time (T) as their fundamental physical quantities. The dimensions of length on Martians' system are:

• A. FT²
• B. F^-1 A² T^-1
• C. F^-1 A^o T^-1
• D. AT²

Answer 1

The correct option is D AT²

$Acceleration=\frac{distance}{tim{e}^2}$
$\Rightarrow A=L{T}^{-2}$
$\Rightarrow L=A{T}^2$
