Assertion For a particle performing SHM, its speed decreases as it goes away from the mean position. Reason In SHM, the acceleration is always opposite to the velocity of the particle.
- A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
- B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- C. Assertion is correct but Reason is incorrect
- D. Both Assertion and Reason are incorrect
Step-by-step solution
In SHM, speed is maximum at mean position and decreases as the particle moves away, so the assertion is correct. However, acceleration is always directed towards the mean position, but it is opposite to velocity only when moving away from mean; when moving towards the mean, acceleration and velocity are in the same direction. Thus, the reason is false.
