Question

A particle executing simple harmonic motion along $y$ -axis has its motion described by the equation $y=Asin\left(\omega t\right)+B$ . The amplitude of the simple harmonic motion is

• A. $A$
• B. $B$
• C. $A+B$
• D. $\sqrt{A+B}$

Answer 1

Answer: (A)

Given equation of simple harmonic motion,
$y=Asin\left(\omega t\right)+B$
Here, $B$ is the mean position of the simple harmonic motion on the $y$ -axis.
The amplitude is the maximum displacement from the mean position.
So, the amplitude of the simple harmonic motion is $A$ .
