Electric field:

$\overline{){\mathbf{E}}{\mathbf{=}}\frac{\mathbf{k}\mathbf{q}}{{\mathbf{r}}^{\mathbf{2}}}}$, where k is Coulomb constant, q is a charge, and r is the distance between the charge to the point where the electric field is to be calculated.

Let's visualize our problem in the figure below:

We need to note that:

E_{1} = E_{2}sinθ

Intuitively, which of the following would happen to Enet if d became very large?

A. E net should reduce to the field of a point charge of magnitude q.

B. E net should reduce to the field of a point charge of magnitude 4q.

C. The larger d becomes, the smaller the magnitude of E net will be.

D. The larger d becomes, the greater the magnitude of E net will be.
