## Homework Statement

## Homework Equations

m= mass per unit length

T = Tension in string

Velocity in a string

$$ V=\sqrt{\dfrac{T}{m}} $$

Where,

Tension in string, $$T= 10\times9.8=98 kN$$

mass per unit length, $$m= \frac{v \times d}{L}=A\times d= 0.012225 kg/m $$

So,$$V = 89.534 m/s$$

.Now the problem is answer should be equal to 50 m/s . Is there any effect of tuning fork on the wave velocity of the string ?
