What happens to electric field near and away from a neutral

  1. Mar 17, 2015 #1
    What happens to the electric field lines near and away from a neutral point. The neutral point of two opposite charges.
    (q1 and -q2)

    I think you need to phrase your question better. For any point in space, I can always imagine an infinite number of distant pairs of charges q1 q2 for which that point is the neutral point.

    The situation is that there are two point charges in vaccum and they have a neutral point and all three are collinear. What would happen to the electric field around that neutral point.

    Can you even have a neutral point with 2 oppositely charged particles?

    OP (Elle885)

    What do you call "neutral point" here?

    It is the point on which if u put a test charge it would be in equilibrium i.e. the attractive and repulsive forces would balance each other.

    Well, then the field is zero at this point. For two opposite charges you have such points only if they have different magnitudes.
    What happens when you go away form such a point depends on how you do it. In what direction you move away.
