Question 35 POST_UTME_REDEEMERS_UNIVERSITY • 2023 • PHYSICS • objective

A simple harmonic motion is described by the equation $x(t) = A \cos\( \omega t + \phi \)$. If the amplitude $A$ is increased from $A_1$ to $A_2$, what is the new phase angle $\phi_{new}$?

Answer Options

A. \phi + \arc\cos \left\( \frac{A_2}{A_1} \right \)
Correct Answer B. \phi + \arc\cos \left\( \frac{A_1}{A_2} \right \)
C. \phi + \arc\sin \left\( \frac{A_1}{A_2} \right \)
D. \phi + \arc\tan \left\( \frac{A_1}{A_2} \right \)
Correct Answer
B
Correct Option:
\phi + \arc\cos \left\( \frac{A_1}{A_2} \right \)
