JEE Main 2025 Physics 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 x0 and initial momentum p0 is enough to determine the position and momentum at any time t for a simple harmonic motion with a given angular frequency ω. Reason (R) : The amplitude and phase can be expressed in terms of x0 and p0. In the light of the above statements, choose the correct answer from the options given below :

• (1)Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
• (2)(A) is false but (R) is true.
• (3)(A) is true but (R) is false.
• (4)Both (A) and (R) are true and (R) is the correct explanation of (A).Correct
