JEE Main 2025 — Oscillations Question with Solution
JEE Main 2025 (28 Jan Shift 2)
Question
Given below are two statements. One is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : Knowing initial position and initial momentum is enough to determine the position and momentum at any time for a simple harmonic motion with a given angular frequency .
Reason (R): The amplitude and phase can be expressed in terms of and .
In the light of the above statements, choose the correct answer from the options given below :
