A body executes simple harmonic motion. The potential energy (P.E.), the kinetic energy (K.E.) and total energy (T.E.) are measured as function of displacement . Which of the following statement is true?
- AK.E. is maximum when
- BT.E. is zero when
- CK.E. is maximum when is maximum
- DP.E. is maximum when
Solution & Step-by-step Explanation
In SHM:At mean position (), velocity is maximum, so K.E. is maximum and P.E. is minimum.At extreme positions (), velocity is zero, so K.E. is zero and P.E. is maximum.Total Energy (T.E.) remains constant throughout the motion.
