A metallic wire of 1 m length has a mass of 10 xx 10^(-3) kg If a tension of 100 N is applied to a wire, What is the speed of transverse wave ? |

Answer» 100 `ms^(-1)` `therefore "" m = (M)/(l)= 10 xx 10^(-3) ` kg/m v = `SQRT((T)/(m)) = sqrt((100)/(10 xx 10^(-3)) ) ` `v = sqrt((100)/(10^(-2))) = sqrt(100 xx 10^(2)) = 100 ` m/s . Correct choice is a. |
