Assertion: Acceleration is proportional to the displacement. This condition is not sufficient for motion in simple harmonic.
Reason: In simple harmonic motion direction of displacement is also considered.
Both assertion and reason are true and the reason is the correct explanation of the assertion.
Both assertion and reason are true but reason is not the correct explanation of the assertion.
Assertion is true but reason is false.
Assertion and reason both are false.
Assertion: Sine and cosine functions are periodic functions.
Reason: Sinusoidal functions repeat it values after a definite interval of time.
Both assertion and reason are true and the reason is the correct explanation of the assertion.
Both assertion and reason are true but reason is not the correct explanation of the assertion.
Assertion is true but reason is false.
Assertion and reason both are false.
Assertion: The periodic time of a hard spring is more as compared to that of a soft spring.
Reason: The periodic time depends upon the spring constant, and spring constant is large for hard spring.
Both assertion and reason are true and the reason is the correct explanation of the assertion.
Both assertion and reason are true but reason is not the correct explanation of the assertion.
Assertion is false but reason is true.
Assertion and reason both are false.
