Q. 9

The equation of motion of a particle is x = a cos (α t )2. The motion is
A. periodic but not oscillatory.

B. periodic and oscillatory.

C. oscillatory but not periodic.

D. neither periodic nor oscillatory.

Answer :


Now differentiating the above twice we get,



Thus, we find that is proportional to and hence it is an oscillatory.



Thus, the motion is not periodic.


Hence the option (c).
