The dimensional formula of pressure is:
- A. \( [ML^{-1}T^{-2}] \)
- B. \( [MLT^{-2}] \)
- C. \( [ML^2T^{-2}] \)
- D. \( [M^2LT^{-2}] \)
Correct Option:
- A. \( [ML^{-1}T^{-2}] \) ✓ Correct
- B. \( [MLT^{-2}] \)
- C. \( [ML^2T^{-2}] \)
- D. \( [M^2LT^{-2}] \)
Hint: Pressure = Force / Area.
Solution:
\( [P] = \frac{[MLT^{-2}]}{[L^2]} = [ML^{-1}T^{-2}] \)
