The dimensions of pressure is:
Correct answer: D. D
- A. A
- B. B
- C. C
- D. D
Explanation
The following is the solution:ππππ π π’ππ = πΉππππ/π΄πππBy dimensional analysis: ππππ π π’ππ = ππ. π. π β2/π2 Therefore, by simplification we get out answer:[MLTβ2]/[L2]=ML-1T-2The correct dimension of pressure: [MLTβ2]/[L2]=ML-1T-2

About Dimensional Analysis
Dimensional analysis expresses physical quantities through fundamental dimensions such as mass, length and time. It checks dimensional consistency, helps derive relations and converts between unit systems, but cannot determine numerical constants or distinguish quantities with identical dimensions. Dimensional formulae must not be confused with complete physical units.
