Marks: +1, -0

In the List-I below, four different paths of a particle are given as functions of time. In these functions,α and β are positive constants of appropriate dimensions and α≠β.In each case,the force acting on the particle is either zero or conservative. In List-II, five physical quantities of the particle are mentioned:

−

is the linear momentum

−

is the angular momentum about the origin, K is the kinetic energy,U is the potential energy and E is the total energy. Match each path in List-I with those quantities in List-II, which are conserved for that path.
