Answer:

the field is not zero anywhere on the x axis (except at infinity)

Explanation:

From the Coulomb's law we have electric field intensity as:

[tex]E=\frac{1}{4\pi.\epsilon_o} \frac{q}{r^2}[/tex]

where:

[tex]\epsilon_o=[/tex] permittivity of free space

[tex]q=[/tex] charge due to which the field is generated.

[tex]r=[/tex] distance from the charge

So, from the above relation:

Electric field due to a charge can only be zero at infinity.
