CBSE Class 12-science Answered
the frequency (f) of an oscillating drop depends upon radius (r)of the drop , density(P)of the liquid and the surface tension(t) of the liquid .find the expression of the frquency(k is the dimensional constant).
a)
F=k*(t/pr^2)^1/3
b)F=k*(t/pr^3)^1/2
c)F=k*(p/tr^3)^1/2
d)None of these
find the right answer

Expert Answer
let frequency, ? = k ra pb tc
Putting the dimensions of quantities, we have
[T-1] = 1 [L]a [ML-3]b [MT-2]c
comparing the powers we have
-2c = -1, c = 1/2;
b + c = 0, b = - 1/2;
a - 3b = 0, a = - 3/2;
Therefore, ? = k sqrt (t / P r3)
So, b is correct.
