1.Units, Dimensions and Measurement
medium
The $SI$ unit of a physical quantity is pascal-second. The dimensional formula of this quantity will be ..............
A$\left[ ML ^{-1} T ^{-1}\right]$
B$\left[ ML ^{-1} T ^{-2}\right]$
C$\left[ ML ^{2} T ^{-1}\right]$
D$\left[ M ^{-1} L ^{3} T ^{0}\right]$
(JEE MAIN-2022)
Solution
Pascal second
$\frac{F}{A} t=\frac{M L T^{-2}}{L^{2}} T=M L^{-1} T^{-1}$
$\frac{F}{A} t=\frac{M L T^{-2}}{L^{2}} T=M L^{-1} T^{-1}$
