Which one of the following equations of motion represent simple harmonic motion? Where `k, k_(0), k_(1)` and a are positive.

Options

A. Acceleration `= -k(x+a)`
B. Acceleration `= k(x+a)`
C. Acceleration `= ka`
D. Acceleration `= -k_(0)x+ k_(1)x^(2)`

Answer

A

Explanation

Acceleration `= -k (x+a)`
From acceleration in SHM `a= -kX`.
where `X= x+a`
