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
A
P.E. is maximum when x = 0
B
K.E. is maximum when x = 0
C
T.E. is zero when x = 0
D
K.E. is maximum when x is maximum
Answer
K.E. is maximum when x = 0
Explanation
Solution
In S.H.M., at mean position i.e. at x = 0 kinetic energy will be maximum and pE will be minimum. Total energy is always constant.
