If in a system force (F), pressure (P) and time(T) is fundamental unit, then dimensional formulae for length will be:

Options

A. `[F P^(-1)]`
B. `[F^(2)P^(-2)]`
C. `[F^(1//2)P^(-1//2)]`
D. none of these

Explanation

`L=[MLT^(-2)]^(x)[ML^(-1)T^(-2)]^(y)[T]^(x)`
`x+y=0 x-y=1`
`-2x-2y+z=0`
`x-(1)/(2) y=-(1)/(2) z=0`
