Question: Consider the electromagnetic gauge transformation A = A + VA and V = V- - A t Show that this changes the Lagrangian exactly

Consider the electromagnetic gauge transformation A = A + VA and V

Consider the electromagnetic gauge transformation A = A + VA and V = V- - A t Show that this changes the Lagrangian exactly as in part (a), and therefore gauge trans- formations do not change the equations of motion of a charged particle. What is F in this case?
