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.
