What is the condition for neutral point due to two point charges of opposite kinds?

Question

anonymous · Answer

where the field lines of both charges cancel out each other

ujjwal · Answer

Do they cancel at any point? Is it even possible??

anonymous · Answer

oh charges of opposite kinds, then that isn't possible...

anonymous · Answer

Its possible ,Yes it will be outside from the line joining the centres.

anonymous · Answer

It will depend on the the magnitude of charges involved..
Neutral point will never be in between. It will be either on the side of one or another.
It will be on the side of that charge having less magnitude. Rest is the matter of calculation & to numerically determine the position of neutral point.

anonymous · Answer

if the two charges have same magnitude but opposite charges then there will not be any neutral point.
