In the Column 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 αβ. In each case, the force acting on the particle is either zero or conservative.
In Column II, five physical quantities of the particle are mentioned: p is the linear momentum L 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 Column I with those quantitites in Column II, which are conserved for that path.
Column~IColumn~II(A) r(t)=α t^i+β t^j1. p(B) r(t)=α cos ω t ^i+β sin ω t ^j2. L(C) r(t)=α(cos ω ^i+ sin ω t^j)3.K(D) r(t)=α t^i+β2t2^j4. U5. E
