A) 2
B) \[2\sqrt{2}\]
C) 4
D) \[2\sqrt{3}\]
E) \[4\sqrt{2}\]
Correct Answer: D
Solution :
The equation of SHM is \[y=A\sin (\omega t+\phi )\] Or \[y=A(\sin \omega t\cos \phi +\cos \omega t\sin \phi )\] ... (i) The given expression is \[y=2(\sin 5\pi t+\sqrt{2}\cos \pi t)\] ...(ii) \[A\cos \phi =2\]and\[A\sin \phi =2\sqrt{2}\] Squaring and adding, we get \[A=2\sqrt{3}\]You need to login to perform this action.
