Question

Two of Maxwell's equations contain an integral over a closedsurface. For them the infinitesimal vectorarea dA is always: tangentto the surface
perpendicularto the surface and pointingoutward     
tangentto a field line
perpendicularto a field line
perpendicularto the surface and pointing inward Two of Maxwell's equationscontain a path integral on the left side and an area integral onthe right. The directions of the infinitesimal pathelement ds and infinitesimal areaelement dA are: alwaysin the same direction
neverperpendicular to eachother     
alwaysin opposite directions
noneof these
alwaysperpendicular to each other tangentto the surface
perpendicularto the surface and pointingoutward     
tangentto a field line
perpendicularto a field line
