When two displacements represented by are superimposed the motion is:
simple harmonic with amplitude
simple harmonic with amplitude
not a simple harmonic
simple harmonic with amplitude
As we learnt in
Superposition of sinusoidal wave -
- wherein
Resultant equation is
Since the frequencies for both S.H.M. are same resultant motion will be S.H.M.
