Wave Mechanics Question 543
Question: A particle of mass 1 kg is moving in S.H.M. with an amplitude 0.02 and a frequency of 60 Hz. The maximum force acting on is
Options:
A) 144 $ {{\pi }^{2}} $
B) 188 $ {{\pi }^{2}} $
C) 288 $ {{\pi }^{2}} $
D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
[c] $ Max.force=mass\times max.acceleration $
$ =m,4,{{\pi }^{2}}v^{2}a=1\times 4\times {{\pi }^{2}}{{(60)}^{2}}\times 0.02 $
$ =288{{\pi }^{2}} $
