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:
0
B) 0.5 A
C) 1.5a
2a
Show Answer
Answer:
Correct Answer: D
Solution:
Initially t=0 $ x=a,\cos ,\pi t=a,\cos ,0= a $ Finally at $ t=3 $
$ x=a,\cos ,3\pi =-a $ Total displacement = 2a
