The derived unit of pressure can be expressed as
- kgms-2
-
kg m-1s-2
- kg m-2s-2
- kg m-1s2
The correct answer is: B
Explanation
Pressure = \(\frac{Force}{Area}\)
Force = mass x acceleration
\(\therefore\) Pressure = \(\frac{mass \times acceleration}{Area}\)
= \(\frac{kg \times m \times s^{-2}}{m^2}\)
= kg m\(^{-1}\) s\(^{-2}\)
