Question

Figure shows a string of linear mass density `1.0 g//cm` on which a wave pulse is travelling. Find the time taken (in milli second) by the pulse in travelling through a distance of `60 cm` on the string. Take `g = 10 m//s^(2)`.

Answer 1

Correct Answer - 30
`V = sqrt((T)/(mu)) = 20 m//s`
`s = Vt`
`t = 0.03` sec
