- Homework Statement
- 3 semi infinite rods are placed along x, y and z axis such that the points on them obey x > 0,y>0 and z>0 and their common end is origin. Find Electric field at (R,R,R)

- Relevant Equations
- None

I tried resolving the semi infinite rods into arcs of 90 degree each placed on the three axes but that doesnt take me anywhere....

Alternatively I tried finding out the field at the point due to each rod but im unable to find the perpendicular distance from the point to the rod...I dont think such a distance exists..I know I should use integration but im having a hard time doing anything in 3d. Can someone give me a starter ..
