3. One reason why we know that the magnetic fields are not the same as electric fields is because the force exerted on a charge q: A) is in opposite directions in electric and magnetic fields B) is in the same direction in electric and magnetic fields C) is parallel to a magnetic field and perpendicular to an electric field D) is parallel to an electric field and perpendicular to a magnetic field E) Is zero in both if the charge is not moving
