1.	Out of the following functions representing motion of a particle which represents SHM I. `y = sin omega t - cos omega t` II. `y = sin^(3)omega t` III. `y = 5 cos ((3 pi)/(4)-3 omega t)` IV. `y = 1 + omega t + omega^(2)t^(2)`A. only(iv) does not represent `SHM`B. (i) and (iii)C. (i) and (ii)D. only (i)
Answer» Correct Answer - B For a simple harmonic motion `(d^(2)y)/(dt^(2)) prop - y` Hence equation `y = sin omega t` and `y = 5 cos ((3pi)/(4) - 3 omegat)` setisfy this contation and equation `y = 1 + omega t + omega^(2) t^(2)` is not peridlum `y = sin^(2)omega^(2)` periode but not `SHM` option c is correct
