  A body executes simple harmonic motion. The potential energy (PE), the kinetic energy (KE) and total energy (TE) are measured as function of displacement\[x\]. Which of the following statements is true?               [AIEEE 2003]

A)  KE is maximum when \[x=0\]

B)  TE is zero when \[x=0\]

C)  KE is maximum when \[x\] is maximum

D)  PE is maximum when \[x=0\]

Correct Answer: A

Solution :

[a] At , kinetic energy is maximum and potential energy is minimum.
