MHT CET 2022 Physics question
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 'R' is the resultant amplitude, match column I with column II Column I A. The two SHMs are in phase, B. The two SHMs are in phase, C. The two SHMs are in phase, D. The two SHMs are out of phase, Column II I. II. III. IV.
Answer: (B)
Solution
Resultant amplitude of two collinear SHMs: , where is the phase difference. A: , gives (III). B: with unequal amplitudes gives (I). C: and $
