Question

3. (a) Find the electric and magnetic fields which corresponding to the following potentials: V (Ft) = 0, A(F,t) = - (b) Find the charge and current distributions which give rise to these potentials. (@) Show that applying the gauge function 1 = - will not affect the fields E and B. (a) Apply the gauge function ) = -d to transform the potentials and comment on what type of charge distribution would give rise to this set of potentials.
