Any smooth surface has two unit normals at each point, if one is then the other is ; they point in opposite directions.
Choose all of the true statements about how this choice of orientation relates to the calculation of surface integrals.

Question

Any smooth surface has two unit normals at each point, if one is then the other is ; they point in opposite directions.

Choose all of the true statements about how this choice of orientation relates to the calculation of surface integrals.

Accepted Answer

Flux integrals will change by a negative sign if the normal is reversed.

Accepted Answer

The normals    and 
   differ by a negative sign.

Accepted Answer

The calculation of area by a surface integral is unaffected by the orientation of the normal.

Answer

The calculation of area by a surface integral will change by a negative sign if the normal is reversed.

Answer

Flux integrals are unaffected by the orientation of the normal.

Answer

The normals    and    are the same.
