1. Given Expression: (f = \frac{1}{2}l\sqrt{\frac{f \cdot l}{m}})
2. Identify the Variables:
3. Write the Dimensions:
4. Analyze the Given Expression:
The left-hand side (LHS) of the equation is (f), which has the dimension ([T^{-1}]).
The right-hand side (RHS) involves several terms:
5. Dimensional Consistency:
Since the LHS and RHS have the same dimension ([T^{-1}]), the formula is dimensionally consistent.
