Q. Which one of the following equations of motion represents simple harmonic motion Where $k,k_{0},k_{1}$ and $a$ are all positive
A) Acceleration $= - k_{0}x + k_{1}x^{2}$
B) Acceleration $= - k(x + a)$
C) Acceleration$\ = k(x + a)$
D) Acceleration$\ = kx$
Explanation
(b) Acceleration in SHM is directly proportional to displacement and is always directed to its mean position
