Question

Assertion: All small oscillations are simple harmonic.
Reason: Oscillations of a simple pendulum system are always simple harmonic whether the amplitude is small or large.

  1. If both the assertion and reason are true but the reason is not the correct explanation of assertion.
  2. If the assertion is false but the reason is true.
  3. If both the assertion and the reason are true and the reason is the correct explanation of the assertion.
  4. If the assertion is true, but the reason is false.

hintHint:

Simple harmonic motion is defined as a periodic motion of a point along a straight line, such that its acceleration is always towards a fixed point in that line and is proportional to its distance from that point.

The correct answer is: If the assertion is false but the reason is true.


    Correct option (d) If Assertion is false but the Reason is true
    Assertion is false as if  F proportional to ̸ space minus x left parenthesis space n o t space p r o p o t i o n a l space t o space right parenthesis then motion will not be SHM.
