Two point charges are separated by a certain distance. Electric field intensity is zero at a point in between the two charges. What can we conclude about the charges ?

Two point charges +Q and -Q are separated by a certain distance. The resultant electric field is parallel to the line joining the charges at the points

Two point electric charges of unknown magnitudes and signs are placed a certain distance apart. The electric field intensity is zero at a point not between the charges but on the line joining them. Write two essential conditions for this to happen.

Two point charges e_(1) and e_(2) are separated by a distance d but the electric field is not 0 on any point joining the two points. What can be concluded from this?

Two point electric charges of unknown magnitude and sign are placed a distance apart. The electric field intensity is zero at a point not between the charges but on the line joining them. Write two essential conditions for this to happen.

Electric field intensity is |vecE| at a distance r from an isolated point charge. Then
