Answer» Correct Answer - C Displacement equation `y=A sin omegat-B cos omemgat` Let `A=a cos theta and B=a sin theta` So, `A^(2)+B^(2)=a^(2)` `Rightarrow a=sqrt(A^(2)+B^(2))` Then, `y=a cos theta sin omega t-a sin theta cos omega t` Which is the equation of simple harmonic oscillator. The amplitude of the oscillator `=a=sqrt(A^(2)+B^(2))` |
