(b) If the Lagrangian of a system is invariant under translation along a direction, the corresponding linear momentum is conserved. (c) If the lagrangian of a system is invariant under translation a long a direction, we cannot say anything about the corresponding linear momentum. (d)For a conservation system, the Hamiltonian is equal to the sum of kinetic and potential energies. Q.3) A particle is moving on elliptical path under inverse square law force of the form F(r)= (-K/r”), the eccentricity of the orbit is (a) A function of total energy. (b) Independent of total energy. (c) A function of angular momentum. (d) Independent of angular momentum.
