A uniform wire of length L , diameter D and density is stretched by a tension T length L and the diameter D is
Options
- Af L D
- Bf 1 L D
- Cf 1 L D
- Df 1 L D^2
Correct answer
B. f 1 L D
Step-by-step solution
Given, Frequency =f , Diameter =D , Length =L , Density = and Tension =T Now, we know that f= c , f= 1 2 L T where is mass per unit length And mass per unit length is related to density via, = ( D^2 4 ) 1 So, the frequency is f= 1 2 L T ( D^2 4 ) f 1 L D
