easy
The dimensions of pressure are
A$ML{T^{ - 2}}$
B$M{L^{ - 2}}{T^2}$
C$M{L^{ - 1}}{T^{ - 2}}$
D$M^{-1}L^{-1}$
(AIPMT-1994) (AIPMT-1990)
Solution
$ML ^{-1} T ^{-2}$
Pressure: $\frac{F \text { orce }}{\text { Area }}=\frac{\left[ MLT ^{-2}\right]}{\left[ L ^2\right]}=\left[ ML ^{-1} T ^{-2}\right]$
Pressure: $\frac{F \text { orce }}{\text { Area }}=\frac{\left[ MLT ^{-2}\right]}{\left[ L ^2\right]}=\left[ ML ^{-1} T ^{-2}\right]$
