Solution

The correct option is A 200
We know, Speed of transverse wave $(v) = \sqrt{\frac{T}{μ}}$

where, T = Tension = 40N and $μ =$ mass per unit length = $\frac{0.01}{10} = 10^{- 3} k g / m$

$\Rightarrow v = \sqrt{\frac{40}{10^{- 3}}} = 200 m / s$

Therefore, A is correct option.

The correct option is A 200We know, Speed of transverse wave (v)=√Tμwhere, T = Tension = 40N and μ= mass per unit length = 0.0110=10−3kg/m ⇒v=√4010−3=200m/sTherefore, A is correct option.

The correct option is A 200
We know, Speed of transverse wave $(v) = \sqrt{\frac{T}{μ}}$

where, T = Tension = 40N and $μ =$ mass per unit length = $\frac{0.01}{10} = 10^{- 3} k g / m$

$\Rightarrow v = \sqrt{\frac{40}{10^{- 3}}} = 200 m / s$

Therefore, A is correct option.
