Concepts Of Physics MCQ Edition [Volume 1]PhysicsIntroduction to Physics
Determine the dimensions of pressure.
Options
- AMLT⁻²
- BML^2T⁻²
- CML⁻²T⁻²
- 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] .
