When is electric field intensity zero? If intensity is zero along a line, it means there are equal charges of same polarity on both sides of line at same distance, and their effective fields neutralize each other.
At which point electric field intensity is zero? There is a spot along the line connecting the charges, just to the “far” side of the positive charge (on the side away from the negative charge) where the electric field is zero. In general, the zero field point for opposite sign charges will be on the “outside” of the smaller magnitude charge.
Can electric field intensity 0? The electric field will be zero at a point nearer to a smaller charge when the system consists of two opposite and unequal charges. The electric field due to a dipole is never zero at any point around the dipole.
Why electric field intensity is zero inside the conductor? The electric field intensity inside a charged conductor is zero because there are no electric lines of force within the conductor.
