A point charge +2 nC is fixed at the origin. A uniform electric field of 5.0 × 10⁴ N C⁻¹ acts along +x. Find the magnitude of the net electric field at a point 0.10 m to the right of the charge on the x-axis.
(Take k = 9 × 10⁹ N m² C⁻².)
a) 6.80×104N C−1 towards +x
b) 5.18×104N C−1 towards +x
c) 4.82×104N C−1 towards +x
d) 5.18×104N C−1 towards −x
