The given equation is correct
Step-by-step explanation:
The given equation is
Where,
n is the frequency
m is mass per unit length
F is force
l is length
If the equation is correct, the dimension on LHS should be equal to the dimensions on RHS
We know that
Dimensions of frequency = [T?¹]
Dimensions of length = [L]
Dimensions of Force = [MLT?²]
Dimensions of mass per unit length = [ML?¹]
Therefore,
Dimensions of LHS in the formula = [T?¹]
Dimensions of RHS in the formula
Thus,
Dimensions of LHS = Dimensions of RHS
Therefore, the equation is correct.
Hope this answer is helpful.
