Finding Potential (Spherical coordinates )

lundi 28 avril 2014

1. . An electric dipole located at the origin in free space has a moment p = 3ax −2ay +az nC·m. Find V at r = 2.5, θ =30◦, φ =40◦.

I find it difficult to solve when its in spherical co-ordinates.





2.Relevent Eq

V =P.(r-r')/( 4∏ε|r−r'|2)(|r-r'|)





I am confused how to find a unit vector on spherical co-ordinate. ie |r-r'|





This que is from william Hayt and page no 100.
