Current Question (ID: 18982)

Question:

$\text{The SI unit of a physical quantity is pascal-second.}$ $\text{The dimensional formula of this quantity will be:}$

Options:

1. $[\text{ML}^{-1}\text{T}^{-1}]$
2. $[\text{ML}^{-1}\text{T}^{-2}]$
3. $[\text{ML}^2\text{T}^{-1}]$
4. $[\text{M}^{-1}\text{L}^3\text{T}^0]$

Solution:

$\text{The dimensional formula of pascal is } [\text{ML}^{-1}\text{T}^{-2}].$ $\text{Therefore, pascal-second is } [\text{ML}^{-1}\text{T}^{-2}] \times [\text{T}] = [\text{ML}^{-1}\text{T}^{-1}].$
