Question

What will be the dimensional formula for mass if we choose length L, time T, and force F and fundamental quantities?

Answer 1

You can't choose force as a fundamental quantitiy because its made up of mass and acceleration(Length and time) but mass is a fundamental quantity as it is not MADE up of any other dimentions.

Answer 2

Force = F

Length = L

Time = T

F = Mass × Acceleration

F = m × a

m = F / a

$m = \frac{f}{ {l}^{1} {t}^{ - 2} } \\ \\ m =f {l}^{ - 1} {t}^{2}$

Take the dimensions in capitals.
