Which of the following functions represent SHM : sin 2 omega t |
|
Answer» SOLUTION :A motion will be SHM if ACCELERATION is directely proportional to its displacement `a=- omega^(2)y` As `y= SIN 2 omega` `rArr v=(dy)/(dt)=2 omega COS 2 omega= omega t` Acceleration `=(d^(2)y)/(dt^(2))=- 4 omega^(2) sin 2 omega t` `=- 4omega^(2)y` So `, y= sin 2 omega t` represent SHM. |
