A simple pendulum performs simple harmonic motion about X = 0 with an amplitude A and time period T. The speed of the pendulum at $\mathrm{X}=\frac{\mathrm{A}}{2}$ will be

• A

  $\frac{\mathrm{\pi A}\sqrt{3}}{\mathrm{T}}$

• B

  $\frac{\mathrm{\pi A}}{\mathrm{T}}$

• C

  $\frac{\mathrm{\pi A}\sqrt{3}}{2\mathrm{T}}$

• D

  $\frac{3{\mathrm{\pi }}^2\mathrm{A}}{\mathrm{T}}$
