Question

If the length and diameter of a wire are decreased, then for the same tension the natural frequency of stretched wire will ______.

Options

• decrease

• become zero

• increase

• not change

Answer 1

If the length and diameter of a wire are decreased, then for the same tension the natural frequency of stretched wire will increase.

Explanation:

Frequency n `=1/(2Lr)sqrt(T/(pirho))`

∴ If L and r decrease, the frequency will increase.
