Physical World Units and Measurements - Result Question 32
34. The dimensional formula of pressure is
(a) $[MLT^{-2}]$
(b) $[ML^{-1} T^{2}]$
(c) $[ML^{-1} T^{-2}]$
(d) $[MLT^{2}]$
[1990]
Show Answer
Answer:
Correct Answer: 34. (c)
Solution:
- (c) Pressure $=$ Force / Area
So dimensional formula
$ =\frac{[MLT^{-2}]}{[L^{2}]}=[ML^{-1} T^{-2}] $
