Question

1 Pascal is

• A. 1$N/m$
• B. 1$m/N$
• C. 1 $Kgms$
• D. 1 $kg{m}^{-1}{s}^{-2}$

Answer 1

The correct option is D

1 $kg{m}^{-1}{s}^{-2}$

Explanation for correct option:

Option (D):

1. Pascal is the unit of pressure.
2. $Pressure=Force/Area.$
3. $1Pa=1N/m^2=(1kgm{s}^{-2})/m^2=kg{m}^{-1}{s}^{-2}.$

4. 1 Pascal is defined as the pressure exerted on an area $1m^2$ by a force of $1N.$

Hence, option (D) is correct.
