Question

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

Select the correct option:

$\left[\mathrm{ML}^{-1} \mathrm{~T}^{-1}\right]$

$\left[\mathrm{ML}^{-1} \mathrm{~T}^{-2}\right]$

$\left[\mathrm{ML}^2 \mathrm{~T}^{-1}\right]$

$\left[\mathrm{M}^{-1} \mathrm{~L}^3 \mathrm{~T}^0\right]$

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

Pascal second $$ \frac{F}{A} \mathrm{t}=\frac{M L T^{-2}}{L^2} T=M L^{-1} T^{-1} $$
