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
Correct Answer: Option 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})
