Question

The density of the material of a wire used in sonometer is 7.5 × 103 kg / m 3. If the stress on the wire is 3.0 × 108 N / m 2, the speed of transverse wave in the wire will be - (A) 100 m/s (B) 200 m/s (C) 300 m/s (D) 400 m/s

d=7.5 × 103 kg / m 3 s =3 × 108 N / m 2 That depends on V =√( P /ρ) =√(3 × 108/7.5 × 103) =200 m / s

Q. The density of the material of a wire used in sonometer is $7.5 \times 1 0^{3} k g / m^{3}$ . If the stress on the wire is $3.0 \times 1 0^{8} N / m^{2}$ , the speed of transverse wave in the wire will be -

100 m/s

200 m/s

300 m/s

400 m/s

$d = 7.5 \times 1 0^{3} k g / m^{3}$
$s = 3 \times 1 0^{8} N / m^{2}$
That depends on $V = \frac{P}{ρ}$
$= \frac{3 \times 1 0 ^{8}}{7.5 \times 1 0 ^{3}}$
$= 200 m / s$
