On the superposition of two harmonic oscillations represented by

{X_1} = a\sin \left( {\omega t + {\phi _1}} \right)

and

{X_2} = a\sin \left( {\omega t + {\phi _2}} \right)

a resulting oscillation with the same time period and same amplitude is obtained. The value of

{\phi _1} - {\phi _2}

View answer and explanation

Correct option: A

120\,^\circ C

Option A (

120\,^\circ C

) is correct because when two oscillations of the same amplitude result in an oscillation of the same amplitude, the phase difference must be 120 degrees.
