One end of a string of length L is tied ...

One end of a string of length `L` is tied to the ceiling of a lift acceleration upwards with an acceleration `2g`. The other end of the string is free. The linear mass density of the string varies linearly from `0 to lambda` from bottom to top. Choose the correct option(s)

A

The velocity of the wave in the string will be 0.

B

The acceleration of the wave on the string will be 3g/4 every where.

C

The time taken by a pulse to reach from bottom to top will be `sqrt(8L //3g)`.

D

The time taken by a pulse to reach from bottom to top will be `sqrt(4L//3g)`.
