Physics Question on Units and measurement

The SI unit of a physical quantity is pascal-second. The dimensional formula of this quantity will be

A

[ML–1T–1][ML^{–1}T^{–1}]

B

[ML–1T–2][ML^{–1}T^{–2}]

C

[ML2T–1][ML^2T^{–1}]

D

[M–1L3T0][M^{–1}L^3T^0]

Answer

[ML–1T–1][ML^{–1}T^{–1}]

Explanation

Solution

=MLT−2L2×T\frac{MLT^{−2}}{L^2}×T [pascal-second]

= ML–1T–1ML^{–1}T^{–1}
