Which of the following is not a correct application of dimensional analysis?
AConverting units from one system to another
BChecking the correctness of an equation
CDeriving the exact numerical constant in a formula
DFinding the dependence of a physical quantity on other quantities
Answer & Solution
Correct answer: C. Deriving the exact numerical constant in a formula
Dimensional analysis can test dimensional consistency, help convert units, and suggest how a quantity depends on others. It cannot determine exact dimensionless numerical constants such as $2$, $\pi$, or $1/2$.
