Question

A steel wire with mass per unit length 7.0 × 10-3 kg m -1 is under tension of 70 N. The speed of transverse waves in the wire will be: (A) 10 m / s (B) 100 m / s (C) 200 π m / s (D) 50 m / s

Tardigrade Admin · Accepted Answer

v=√(T/μ)=√(70/70 × 10-3)=100 m / s

Q. A steel wire with mass per unit length $7.0 \times 1 0^{- 3} k g m^{- 1}$ is under tension of $70 N$ . The speed of transverse waves in the wire will be:

$10 m / s$

$100 m / s$

$200 πm / s$

$50 m / s$

$v = \frac{T}{μ} = \frac{70}{70 \times 1 0 ^{- 3}} = 100 m / s$

Q. A steel wire with mass per unit length 7.0×10−3kgm−1 is under tension of 70N. The speed of transverse waves in the wire will be:

10m/s

100m/s

200πm/s

50m/s
