The derived unit of pressure can be expressed as
A
kgms-2
B
kg m-1s-2
C
kg m-2s-2
D
kg m-1s2
Verified Correct Answer: B.
Physical Principles & Numerical Solution
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\(^{-2}\)
