Wave Mechanics Question 572

Question: If a particle takes 0.5 sec to reach position of minimum velocity from previous such position, then

Options:

A) $ T=6\sec ,,v=1/6,Hz $

B) $ T=2\sec ,,v=1,Hz $

C) $ T=3\sec ,,v=3,Hz $

D) $ T=1\sec ,,v=1,Hz $

Show Answer

Answer:

Correct Answer: D

Solution:

[d] $ \frac{T}{2}=0.5\sec \Rightarrow T=1\sec $

$ v=\frac{1}{T}=1,Hz $
