NEET2002PhysicsOscillationsActual
Assertion : In simple harmonic motion, the motion is to and fro and periodic. Reason: Velocity of the particle (v)= k^2-x^2 (where x is the displacement).
Options
- AIf both the assertion and reason are true and reason is a correct explanation of the assertion.
- BIf both assertion and reason are true but assertion is not a correct explanation of the assertion.
- CIf the assertion is true but the reason is false.
- DIf both assertion and reason are false.
Correct answer
B. If both assertion and reason are true but assertion is not a correct explanation of the assertion.
Step-by-step solution
Aparticle is said to execute simple harmonic motion, if it moves to and fro about a fixed point under the action of a restoring force which is directly proportional to its displacement from the fixed point and is always directed towards the fixed point. Also the velocity of the particle when its displacement is x, v= k^2-x^2 .
