The impulse J required to bring it to rest when it reaches the vertical position :
(A) Impulse is m?gl/3 when it is applied horizontally at distance l from pivoted point
(B) Impulse is 2m?gl/3 when it is applied horizontally at distance l/2from pivoted point
(C) Minimum impulse is m?gl/2 when it is applied at distance l from pivoted point
(D) If rod is stopped by applying minimum impulse then the impulse imparted by pivot is m?gl/2?3
