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

Options

  1. AFL⁻¹
  2. BF^2L⁻²
  3. CFL⁻²
  4. DFL⁻³

Correct answer

C. FL⁻²

Step-by-step solution

Pressure is defined as force acting per unit area. P = F A The dimensional formula for area is L^2 . Substituting the fundamental dimensions of force and area, we get: [P] = F L^2 = FL⁻²
