A uniform metal wire has length ' L ', mass ' M ' and cross-sectional area ' A '. It is under tension ' T ' and ' V ' is the speed of transverse wave along the wire. The density of the wire
Options
- AA T V^2
- BT A^2 V
- CT V^2 A
- DV^2 A^2 T
Correct answer
C. T V^2 A
Step-by-step solution
For transverse waves on a wire V= T m The mass per unit length can be written as m= M L = A L L =A aligned & V= T m = T A & V^2= T A & A= T V^2 aligned
