Question

Equation of wave on string of linear mass denisity 0.04kg/m is given by y= 0.02m(sin[2π(t/0.04(s) - x/0.59(m))] the tension in the string is ? [AIEEE 2010] ​

Answer 1

Explanation :- Given mass denisity μ = 0.04kg/m

Explanation :- Given mass denisity μ = 0.04kg/m ω = 2π/(0.004)²

Explanation :- Given mass denisity μ = 0.04kg/m ω = 2π/(0.004)² k = ( 2π)/(0.50)²

As we know that , V = √T/μ

Τ = μ v² (As we know that v = ω/k)

T = μ × ω²/k² = 0 .04 (2π/0.004)²/(2π/0.50)²
