The x-t graph of a particle performing simple harmonic motion is shown in the figure. The acceleration of the particle at \(t = 2s\) is
(1). \(\displaystyle \frac{-π^2}{8} ms^{-2}\)
(2). \(\displaystyle \frac{π^2}{16}ms^{-2}\)
(3). \(\displaystyle \frac{-π^2}{16} ms^{-2}\)
(4). \(\displaystyle \frac{π^2}{8} ms^{-2}\)
