Assertion: All small oscillations are simple harmonic in nature.
Reason: Oscillations of spring block system are always simple harmonic whether amplitude is small or large.
Reason: Oscillations of spring block system are always simple harmonic whether amplitude is small or large.
View answer and explanation
Correct option: D
If Assertion is false but the Reason is true
Option D (If Assertion is false but the Reason is true) is correct because not all small oscillations are simple harmonic, but oscillations of a spring-block system are always simple harmonic.

Assertion: A particle executing simple harmonic motion comes to rest at the extreme positions.
Reason: The resultant force on the particle is zero at these positions. A particle is subjected simultaneously to two SHM’s one along the -axis and the other along the -axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute A particle is executing SHM with amplitude . When the PE of a particle is one-fourth of its maximum value during the oscillation, its displacement from the equilibrium position will be The displacement, velocity and acceleration in a simple harmonic motion are related as the Assertion: Angular velocity of earth around sun is lesser than the angular velocity of moon about earth.
Reason: Time taken by moon revolve around earth is less than time taken by earth to revolve around sun. A particle is executing . At a displacement its potential energy is and at a displacement its potential energy is . The potential energy of the particle at displacement is
