A body executes simple harmonic motion. The potential energy (P.E), the kinetic energy (K.E) and total energy (T.E) are measured as a function of displacement $x$. Which of the following statements is true?\\
(1) K.E. is maximum when $x = 0$\\
(2) T.E is zero when $x = 0$\\
(3) K.E is maximum when x is maximum\\
(4) P.E. is maximum when $x = 0$
