A mobile postive point charge is located between two parallel charged plates of charge densitys +o (top plate) and -o (bottom plate) at a distance d from the negative plate.the distance doubles (becomes 2d)between the negative (bottom) plate and the mobile charge...

will the magnitude of the electric charge become 1/4 of the initial value? or does it change in a different way?

3. No. Neglecting fringing about the plates (assume they are infinite in direction), E is determined by charge alone.

E between parallel plates= areachargedensity/epsilion
