NEET Physics Simple Harmonic Motion Assertion Reason Question
Assertion (A): The motion of a simple pendulum is simple harmonic only for small angular displacements.
Reason (R): For small angular displacements, sinθ can be approximated as θ, which leads to a restoring torque proportional to the angular displacement.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
For small angular displacements, the approximation sinθ ≈ θ is valid, making the motion simple harmonic as the restoring torque is proportional to displacement. This is stated in Chunk 4.
