Concept used: - here we use the field due to a charge at a point and find the component of the field along the axes in the Cartesian coordinate system, A) E_1 Vector = Vertical-bar -10nc Vertical-bar /4piE_0 a^2 (-j^hat) = 0 i^hat - 1.0 times 10^5 j^hat N/C r = squareroot a^2 + b^2 B) tan theta = a/b or theta = 36.87 degree E_2 Vector = Vertical-bar -10nc Vertical-bar /4 pi E_0 r^2(-cos theta i^hat - sin theta j^hat) = -28800i^hat - 21600j^hat N/C C) E_3 Vector = Vertical-bar -10nc Vertical-bar /4 pi E_0 b^2 (-i^hat) = -56250 i^hat + 0j^hat N/C
