Find electric field at point A, B, C, D due to infinitely long uniformly charged wire with linear charge density `lambda` and kept along z-axis (as shown in figure). Assume that all the parameters are in S.l. units.

Answer» `E_(A)=(2 K lambda)/(3) (hat(i)) implies E_(B)=(2 K lambda)/4 (hat(j))`
`E_(c)=(2 K lambda)/5 overset(^^)(OC)=(2 K lambda)/5((3hat(i)+4hat(j))/5)" "E_(D)=(2 k lambda)/5((3 hat(i)+4hat(j))/5)" "implies E_(D)=E_(C)`
