A stretched wire is kept near the open end of a closed pipe 0.75 m long. The wire is 0.3 m long and has a mass of 0.01 kg. The wire is made to vibrate in its fundamental node, after Ixing at both ends. It sets the air column in the tube hito vibration at its fundamental frequency by resonance. Find (a) the frequency of oscillation of the air column and 6) the tension in the wire. Velocity of sound =330 m/s.

Explanation

To solve the problem step by step, we will break it down into two parts: finding the frequency of oscillation of the air column and then calculating the tension in the wire.

### Step 1: Calculate the frequency of oscillation of the air column

The fundamental frequency of a closed pipe can be calculated using the formula:

\[
f_c = \frac{V}{4L}
