The correct answer is 1.63m.
The force operating on a charged body of unit charge placed at that spot is the electric field resulting from a point charge at that location. The external work required to move a unit charge against an electric field by an infinitesimally small distance without experiencing any acceleration is known as the electric potential due to a point charge.
The force that exists between two different electric charges is the subject of Coulomb's law. The basic idea behind an electric field states that an electric charge changes the environment around it by creating an electric field.
E=kq/d^2
E=14N/C
14=kq/d^2
d^2=(9×10^9)(5.05×10^-9)/14
d^2=√(9×10^9)(5.05×10^-9)/14
d=1.63m
