Current Question (ID: 11300)

Question:

$\text{Which of the following relationships between the acceleration } a \text{ and the displacement } x \text{ of a particle involves simple harmonic motion?}$

Options:

1. $a = 0.7x$
2. $a = -200x^2$
3. $a = -10x$ (Correct)
4. $a = 100x^3$

Solution:

$\text{Hint: For simple harmonic motion } a = -\omega^2 x$ $\text{Explanation: The acceleration of the particle performing SHM is given by,}$ $a = -\omega^2 x \Rightarrow a \propto x$ $\text{Therefore, the acceleration of the particle is performing SHM is } a = -10x.$ $\text{Hence, option (3) is the correct answer.}$
