(b) Consider Lagrangian
Lof an
Nparticle system. Show that total momentum of this system will be conserved if the Lagrangian remains invariant under translation
vec(r)_(i)longrightarrowvec(r)_(i)+vec(d)(Homogeneity of space), here
vec(d)is an arbitrary small constant translation vector. (c) Hamiltonian
H=H(q_(i),p_(i),t)and the canonical equations of motion :
q_(i)^(?)=(delH)/(delp_(i))and
p_(i)^(?)=-(delH)/(delq_(i)). Using Legendre transformation find out Lagrangian
L=L(q_(i),q_(i)^(?),t).
