NEET Physics Question - Oscillation

Assertion (A): In resonance amplitude is infinity, in presence of dissipative forces.

Reason (R): At resonance driving frequency is equal to natural frequency of the system.

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 false. In the presence of dissipative forces, the amplitude at resonance is finite, not infinite. Reason (R) is true. At resonance, the driving frequency matches the natural frequency of the system. Thus, (A) is false and (R) is true.
