A uniform string of length 20 m is suspended from a rigid support. A short wave pulse is introduced at a lowest end. It starts moving up the string. The time taken to reach the support is?

The tension in a string is given as Tx = λxg

Where λ is the linear mass density which is the function of length x

The velocity of wave when it is at a position x is

vx = √Tx/λ = √gx

dx/dt = √gx

T = 2√2s
