, 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
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.
