A wave pulse passing on a string with speed of `40cms^-1` in the negative x direction has its maximum at `x=0` at `t=0`. Where will this maximum be located at `t=5s`?

Text Solution

Verified by Experts

The correct Answer is:
A, B
`v=40cm/sec`
As velocity of a wave is constant location of maximum after 5 sec.
`=40xx5`
`=200 cm along negative x-axis.
`rarr at x=-2m`
