Does not exist

Vedclass · Answer

(A) neutral point is a point where the net electric field is zero. For two point charges $q_1$ and $q_2$,the electric field at any point is the vector sum of the fields produced by each charge. For two charges of equal magnitude but opposite sign ($+q$ and $-q$),the electric field lines originate from the positive charge and terminate at the negative charge. At any point on the line joining the charges,the electric fields due to both charges point in the same direction (away from $+q$ and towards $-q$),so the net field cannot be zero. At any point outside the line joining the charges,the vectors of the electric fields do not cancel each other out to zero. Therefore,there is no point in space where the electric field due to these two charges is zero. Thus,the neutral point does not exist.
