Question

Is it possible for the electric field between two positive charges to equal zero along the line joining the two charges?

Answer 1

Answer:

Yes electric field between the line joining may be zero when both the charges are of opposite magnitude  

Explanation:

Electric field due to a point charge is given by $E=\frac{1}{4\pi \epsilon _0}\frac{Q}{r^2}$

From the relation of magnitude of electric field we can see that magnitude of electric field depends upon the m,magnitude of charge and distance between them

So electric field between the line joining may be zero when both charges are of opposite magnitude ( Means if one charge is positive then other is negative )
