Highly selective Backlog Qs for JEE MainPhysicsOscillations
Out of the following functions representing motion of a particle which represents SHM I. y= t- t II. y= ^3 t III. y=5 ( 3 4 -3 t ) IV. y=1+ t+ ^2 t^2
Options
- AOnly (IV) does not represent SHM
- B(I) and (III)
- C(I) and (II)
- DOnly (I)
Correct answer
B. (I) and (III)
Step-by-step solution
For a simple harmonic motion d^2 y d t^2 -y Hence, equation y= t- t and y=5 ( 3 4 -3 t ) are satisfying this condition and equation y=1+ t+ ^2 t^2 is not periodic and y= ^3 t is periodic but not SHM. Option (3) is correct
