सरल आवर्त गति (Simple Harmonic Motion) कर रहे किसी पिंड का उसकी माध्य स्थिति (mean position) से अधिकतम विस्थापन क्या कहलाता है?

Given below are two statements, one is labelled as Assertion (A) and the other is labelled as Reason (R). In light of the statements, choose the correct answer: Assertion (A): In simple harmonic motion, the potential energy of the particle is maximum at the extreme positions. Reason (R): At the extreme positions, the velocity of the particle is maximum.

If V, A, and X are the velocity, acceleration, and displacement respectively of a particle executing simple harmonic motion, then at the mean position:
