I want to confirm this, for any position vector.(adsbygoogle = window.adsbygoogle || []).push({});

1) They are radial vector that start from the origin to a point in space.

2) IfAis a position vector:

[tex] \nabla X \vec A \;=\; 0 \;\hbox { and }\; \nabla \cdot \vec A \;\hbox { not equal to zero. }[/tex]

3) Any position vector in spherical coordinates contain only [itex]\hat R[/itex] term:

[tex] \vec A _{(x,y,z)} = \vec A_{(R,\theta,\phi)} = \hat R A_R \;\hbox { with }\; A_R=|\vec A| [/tex]

Am I correct?
