Question
The dimensions of pressure is:
Options
- A
A
- B
B
- C
C
- D
D
Explanation
The following is the solution:
๐๐๐๐ ๐ ๐ข๐๐ = ๐น๐๐๐๐/๐ด๐๐๐
By dimensional analysis: ๐๐๐๐ ๐ ๐ข๐๐ = ๐๐. ๐. ๐ โ2/๐2
Therefore, by simplification we get out answer:
[MLTโ2]/[L2]=ML-1T-2
The correct dimension of pressure: [MLTโ2]/[L2]=ML-1T-2
Incorrect as per the formula
Incorrect as per the formula
Incorrect as per the formula
The following is the solution:
The correct dimension of pressure:
[MLTโ2]/[L2]
=ML-1T-2
