A point charge is brought in an electric field. The electric field at a nearby point: This question has multiple correct options

1. Will increase if the charge is positive
2. Will decrease if the charge is negative
3. May increase if the charge is positive
4. May decrease if the charge is negative

Correct answer: May increase if the charge is positive

Solution

A positive point charge creates an electric field pointing away from itself, so at a nearby point its contribution can either add to or oppose the original field depending on geometry. Therefore the field at that point may increase, but it is not guaranteed to always increase.
