Homework Statement
A plane of charge lies in the xz-plane at the origin. Its surface charge density is =4.57 uC/m^2; other charges are present in the vicinity as well. Just to the right of the origin the y-component of the electric field is 520,000N/C. What is the y-component of the electric field just to the left of the origin. Answer must take into account direction of field (left negative, right positive).
Eright = 520000
σ = 4.57 uC/m^2
Homework Equations
Enet = σ/ 2 ε0
Enet = Eright + Eleft
The Attempt at a Solution
I started with Enet = σ/ 2 ε0 = 258070
Eright = 520000
so via Algebra, Eleft = -261930
The sum of Eleft and Eright should be 258070,
what am I doing wrong?
Thanks...
