Question

In non zero electric field electric fluc may be zero but its vic

Answer 1

Answer:

Field, in general, is a region of influence of an particle or object which results in some effects on another particle if present within finite range of the field.

Similarly, Electric field is the region of influence of a charged particle, that is, if any other charged particle is brought in the region of electric field generated by the first particle, the first particle exerts a force (electrostatic force) on it.

Electric field due to a system of charges can be understood by Coulumb’s law. As for your question, for a system of equal and opposite charges separated by a small distance (this is called a dipole), the electric field at any point is given by:

Consider the following electric dipole AB having dipole moment p. Let the point of interest is at a distance r from the centre O of the dipole. Let the line OP makes an angle θ with the direction of dipole moment p.
