NEET Physics Question - Oscillation

Assertion (A): Under forced oscillation external periodic force apply to sustain the motion.

Reason (R): Under forced oscillation phase of harmonic motion of the particle differs from the phase of the driving force.

Both (A) & (R) are true and the (R) is the correct explanation of the (A)

Both (A) & (R) are true but the (R) is not the correct explanation of the (A)

(A) is true but (R) is false

Both (A) and (R) are false

Solution:

Assertion (A) is true: Forced oscillations involve an external periodic force to maintain motion. Reason (R) is true: In forced oscillations, a phase difference exists between the driving force and the particle's motion. (R) describes a property of forced oscillations, but doesn't explain the reason for applying the external force as stated in (A).
