Question

5. Explain any one limitation of dimensional analysis with suitable example.(2)​

Answer 1

It doesn't give information about the dimensional constant. The formula containing trigonometric function, exponential functions, logarithmic function, etc. cannot be derived. It gives no information about whether a physical quantity is a scalar or vector.

Answer 2

Dimensional Analysis can't derive relation or formula if a physical quantity depends upon more than three factors having dimensions. It can't derive a formula containing trigonometric function, exponential function, and logarithmic function and it can't derive a relation having more than one part in an equation.
