Question 64 of 194

If x,vx, v and a denote the displacement, the velocity and the acceleration of a particle executing simple harmonic motion of time period T\mathrm{T}, then, which of the following does not change with time?

Show answer and solution

Answer: (B) aTx\frac{a T}{x}

 aT X=ω2XTX=4π2 T2×T=4π2 T= constant. \frac{\text { aT }}{\mathrm{X}}=\frac{\omega^2 \mathrm{XT}}{\mathrm{X}}=\frac{4 \pi^2}{\mathrm{~T}^2} \times \mathrm{T}=\frac{4 \pi^2}{\mathrm{~T}}=\text { constant. }
