Question: In a region of free space the electric field at an instant of time is E = (80.0i + 32.0j) 64.0k) N/C and the magnetic

In a region of free space the electric field at an instant of time is E = (80.0i + 32.0j) 64.0k) N/C and the magnetic field is B = (0.200i + 0.080 0j + 0.290k) μT.
(a) Show that the two fields are perpendicular to each other.
(b) Determine the Poynting vector for these fields.
