Determine the dimensions of pressure.

Options

  1. AMLT⁻²
  2. BML^2T⁻²
  3. CML⁻²T⁻²
  4. DML⁻¹T⁻²

Correct answer

D. ML⁻¹T⁻²

Step-by-step solution

Pressure is defined as force per unit area. The dimensional formula of force is [MLT⁻²] . The dimensional formula of area is [L^2] . Therefore, the dimensional formula of pressure is [MLT⁻²] [L^2] = [ML⁻¹T⁻²] .
