Homework Statement
Consider a generic point (-x,0,0). Calculate the distancrs of this point from all charges:
q at (-a,0,a)
q at (a,0,,a)
-q at (-a,0,-a)
-q at (a,0,-a)
and calculate the total electric field generated by each of them in terms of these distances, and the magnitude of the electric field produced by each charge. Find the z component of the total electric field
Homework Equations
E=(1/4pi*epsilon0)(q/r^2)*r-hat
The Attempt at a Solution
distance of q from charge -a,0,a:
=sqrt(2a^2 +x^2 -2ax)
distance from charge (-a,0,-a)
=sqrt(-2ax+x^2)
distance from charge (a,0,a)
=sqrt(2a^2 +x^2 +2ax)
distance from charge (-a,0,-a)
=sqrt(2a^2 +x^2 -2ax)
but I don't know how to use the equation to calculate the electric field because the r-hat term in the equation confuses me. please help
