उत्तर
Statement A is more appropriate because the energy of a system in simple harmonic motion is given by \[E = \frac{1}{2}m \omega^2 A^2 .\]
If the mass (m) and angular frequency (ω) are made constant, Energy (E) becomes proportional to the square of amplitude (A2).
i.e. E ∝ A2
Therefore, according to the relation, energy increases as the amplitude increases.
