A uniform metal wire of density p, cross-sectional area A and length i is stretched with a tension T. The speed of transverse wave in the wire is given by

• A

  $\sqrt{\left(\frac{\mathrm{Tl}}{\mathrm{\rho A}}\right)}$

• B

  $\sqrt{\left(\frac{\mathrm{T\rho }}{\mathrm{Al}}\right)}$

• C

  $\sqrt{\left(\frac{\mathrm{T}}{\mathrm{\rho l}}\right)}$

• D

  $\sqrt{\left(\frac{\mathrm{T}}{\mathrm{A\rho }}\right)}$
