Question

Which of the following is correct statement about the magnitude of the acceleration $a$ of the particle executing simple harmonic motion?

• A. a will be maximum at the equilibrium position
• B. a will be maximum at the extreme position
• C. a will be always constant
• D. a will always be zero

Answer 1

Answer: (B)

a will be maximum at the extreme position

Answer 2

During execution of a simple harmonic motion
$|a| \propto x \Rightarrow|a|_{\max } \propto x_{\max }$
Thus, acceleration is maximum at extreme position.
