If the lenghts and diameter of a wire decreased, then for the same the natural frequency of the stretched wire

A

will decrease

B

will increase

C

will not change

D

may increase or decrease

Text Solution

Verified by Experts

The correct Answer is:
B

`n = 1/(2 Lr) sqrt(T/(pi rho))`, if L and r are decreased, n is increased.
