Question

What are the limitation of Dimensional formula? By assuming that the frequency y of a

vibrating string may depend upon

(i) Tension

(ii) length (l)

(iii) mass per unit

length (m), prove that γ ∝ 1/L √F/M​

Answer 1

Answer:

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