A charged particle with some initial velocity is projected in a region, where non-zero non varying uniform and/or magnetic fields are present. In list-I, information about existence of electric and/or magnetic field and direction of initial velocity of charged particle are given in List-II, the probable path of charged particle is mentioned. Match the entries of List-I with entries of List-II (consider gravity free space) {:("List-I","List-II"),(P. vec(E ) = 0. vec(B) = 0"and initial velocity is at an unknown angle with" vec(B),1. "Parabola"),(Q. E != 0. vec(B) = 0 "and initial velocity is at known angle with" vec(E ),2."circular"),(R. vec(E ) != 0. vec(B) != vec(E ) || vec(B ) "and initial velocity is perpendicular to" vec(E ),3. "Helical path with non uniform pitch"),(S. vec(E ) != 0. vec(B) = 0. vec(E ) "perpendicular to" vec(B) "and initial velocity is perpendicular to both" vec(E ) "and" vec(B), 4. "cycloid"):}
