PD Between two charged plates

Stupid question, nonetheless, I will ask it :

Supposing I have two charged plates set up with a gap of a distance of xm between them.

These plates are parallel and the elctric field between them is uniform.

Supposing the PD on one plate is +5V and the other is -5V.

What is the electric field strength in terms of x ?
Hello ?
The field strength is always the potential difference divided by the distance between the two plates for a parallel plate capacitor.

Yes, I know that.

Why is the answer 10/x ??

Could you look at this please :

because the formula is E = v/d

Yes I know that, but shouldnt it be 5/x ??

Because the potential difference is 10V.

Ahhhhh..... I see now.

Could you have a look at the other thread, please ?
