Two equations of two S.H.M. are

y = a\sin \left( {\omega t - \alpha } \right)

and

y = b\cos \left( {\omega t - \alpha } \right)

The phase difference between the two is

View answer and explanation

Correct option: C

90^\circ

Option C (

90^\circ

) is correct because converting sine to cosine reveals a phase difference of

\frac{\pi}{2}

between the two SHM equations.

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

x

-axis and the other along the

y

-axis. The two vibrations are in phase and have unequal amplitudes. The particle will execute A particle is executing SHM with amplitude
