0The velocity of a transverse wave that travels along
\( \mathrm{P} \)
a stretched wire is \( 50 \mathrm{~ms}^{-1} \) when stretching force in
W
it is \( 10 \mathrm{~N} \). The linear density of that wire is
(1) \( 0.4 \times 10^{-3} \mathrm{kgm}^{-1} \)
(2) \( 4 \times 10^{-2} \mathrm{kgm}^{-1} \)
(3) \( 0.4 \mathrm{~g} \mathrm{~cm}^{-1} \)
(4) \( 0.04 \mathrm{~g} \mathrm{~cm}^{-1} \)
