Wave Mechanics Question 551
Question: For a particle moving according to the equation $ x=a,\cos ,\pi ,t $ , the displacement in 3 s is
Options:
A) 0
B) 0.5a
C) 1.5a
D) 2a
Show Answer
Answer:
Correct Answer: D
Solution:
[d] Initially t=0 $ x=a,\cos ,\pi t=-a,\cos ,0^{o}=a $ Finally at $ t=3 $
$ x=a,\cos ,3\pi =-3a $ Total displacement = 2a
