Question

A metallic wire of 1 m length has a mass of 10 × 10⁻³ kg. If the tension of 100 N is applied to a wire, what is the speed of the transverse wave?

Options

• 100 m/s

• 10 m/s

• 200 m/s

• 0.1 m/s

Answer 1

100 m/s

Explanation:

Liner mass density (µ) = `"M"/"L" = (10 xx 10^-3)/1` ⇒ 10⁻²

Speed = `sqrt("T"/µ) = sqrt(100/10^-2)`

V = 100 m/s
