Assuming force, length, and time to be the fundamental quantities, determine the dimensions of pressure.

Options

A $FL^{-1}$
B $F^2L^{-2}$
C $FL^{-2}$
D $FL^{-3}$

Correct answer

C. $FL^{-2}$

Step-by-step solution

Pressure is defined as force acting per unit area.

P = \dfrac{F}{A}

The dimensional formula for area is

L^2

.

Substituting the fundamental dimensions of force and area, we get:

[P] = \dfrac{F}{L^2} = FL^{-2}
