Assertion : A particle performing SHM at certain instant is having velocity v. It again acquire a velocity v for the first time after a time interval of T second. Then the time period of oscillation is T second. Reason : A particle performingSHM can have same velocity at two instants in one cycle.

Answer»

If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
If both Assertion and Reason are correct but Reason is NOTTHE correct explanation of Assertion.
If Assertion is true but Reason is FALSE.
If Assertion is false but Reason is true.

Solution :(d) `t_(PQ)=T""`(given)
But `t_(PQ)` is not the time PERIOD of oscillation.
