Why, when we find electric field inside a capacitor it is q/(E°A) ,while , we take it as q/(2E°A) for finding electric force between the plates of capacitor?

Dear student 
We take the Force as q/(2E°A) because m, one capacitor has q charge and another caacitor has -q chrge , 
This is the resultant force due to two chaeges, 
While the electric field depends upon the dielectric material  inside the capacitor . 
Hope this clears
