$\huge\rm{\underline{\underline{\blue{ Question :- }}}}$

Taking force, length and time to be the fundamental quantities find the dimensions of:-

(a) density

(b) pressure

(c) momentum

(d) energy

Answer:-

(a) density :- [M]^1 [L]^-3

(b) pressure:- [M]^1 [L]^-1 [T]^-2.

(c) momentum:- [M]^1 [L]^1 [T]^-1

(d) energy:- [M]^1 [L]^2 [T]^-2.
