Question
The dimensions of pressure is:
Options
- A
A
- B
B
- C
C
- D
D
Explanation
The following is the solution:
𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 = 𝐹𝑜𝑟𝑐𝑒/𝐴𝑟𝑒𝑎
By dimensional analysis: 𝑃𝑟𝑒𝑠𝑠𝑢𝑟𝑒 = 𝑘𝑔. 𝑚. 𝑠−2/𝑚2
Therefore, by simplification we get out answer:
[MLT−2]/[L2]=ML-1T-2
The correct dimension of pressure: [MLT−2]/[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:
[MLT−2]/[L2]
=ML-1T-2
