A particle moves with position vector given by `r=3t^(2)hat(i)+4hat(j)` where r is measured in metres and t in seconds. For `t gt0`. Match the entries in Column I with those in Column - II.
`{:(" Column-I"," Column-II"),("(A) Angular acceleration","(P) increase with time"),(" (about the axis passing through the origin)",),("(B) Liner momentum of the particle ","(Q) decrease with time"),("(C) Angular speed of the particle about the axis passing through the origin","(R) constant in time"),("(D) Magnitude of angular momentum of the particle with respect the origin is ","(S) directly proportional to the time."),(,"(T) is along negative axis "):}`

Answer
