consider..

If I'm trying to find the voltage at point P due to a linear charge density of length L (the white line that lies on the x axis):

then how come it is incorrect to do the following?

$$V=\int{\vec{E_{x}}dx}+\int{\vec{E_{z}}dz}$$?

(the r vector is just to find dE at each point on the charge density of length L)
