Answer 1

Answer:

(✓F)/l(✓m)

Explanation:

It is given that frequency depends on Force, length and mass per unit length.

f= k F^a l^b m^c (taking k to remove proportionality sign)

Now substitute the dimensional formulas of F, l and m. ( it's mass per unit length. so take ml-¹)

and find the values of a, b and c.
