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:
where:
permittivity of free space
charge due to which the field is generated.
distance from the charge
So, from the above relation:
Electric field due to a charge can only be zero at infinity.
