Problem: 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.

FREE Expert Solution

Electric field:

E=kqr2, 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:

E1 = E2sinθ
