In the above question, the displacement of particle at t = 1 sec and x = 4 cm is:

A

4 cm

B

2cm

C

1cm

D

Zero

Text Solution

Verified by Experts

The correct Answer is:
B
We use `y = a sin" (2pi)/(lambda)(vt - x)`
`y = 2sin" (2pi)/(lambda) (24t - x)`
t = 1, x = 4cm
`y = 2sin ((2pi)/(16) xx20)`
= `2sin(2pi + (pi)/(2)) = y = 2cm`
