Question

two wires A and B of equal length differ only in their thockness.A is thinner than B. if both arae pluckead with same force,then:
(a) a will produce sound of higher pitch than B
(b) a will produce sound of lower pitch than B
(c) both will produce sounds of equal pitch
(d) none of these

Answer 1

The answer is "B". Because the sound produced by a thing depends apoon the density or thickness of its.

Answer 2

Answer:

The wire with a lesser thickness will produce a sound of greater pitch.

Explanation:

Pitch is directly proportional to frequency P∝F.

Since frequency of a string =  1/2*length $\sqrt{Tension/Pi*r^{2}*d }$

Therefore on decreasing the r(radius of cross section), the frequency increases and hence the pitch increases.
