Consider two SHMs along the same straight line 
, where 
and 
are their amplitudes and 
and 
are their initial phase angle. If the two SHMs meet simultaneously and ' 
' is the resultant amplitude, match column I with column II.
Column-I | Column-II | ||
A. | The two SHMs are in phase, A1=A2=A | I. | |
B. | The two SHMs are in phase, A1≠A2 | II. | |
C. | The two SHMs are 90 out of phase, A1=A2=A | III. | |
D. | The two SHMs are 180∘ out of phase, A1=A2 | IV. |
