Show that the gauge transformation in electromagnetic field maps the L to an equiv- alent Lagrangian L', where L' = L+ dFG) and F(q, t) is a function of generalised coordinates (q;) and time t. Using the aforesaid Lagrangian calculate the generalised momentum and obtain the Hamiltonian of the charged particle moving in electromagnetic field.
