Answer

Explanation:

Step1: Recall electric - field formula

The electric - field strength (E) due to a point charge (q) at a distance (d) from the charge is given by Coulomb's law for the electric field. The force between two charges (F = \frac{kq_1q_2}{d^{2}}). For the electric field due to a source charge (q) (where we consider a test - charge (q_0) and (E=\frac{F}{q_0})), the formula for the electric field strength of a point charge is (E=\frac{kq}{d^{2}}), where (k) is the electrostatic constant, (q) is the source charge, and (d) is the distance from the source charge.

Answer:

(E = \frac{kq}{d^{2}}) (the third option)
