Q) Two parallel plates are 8cm apart and are appositely charged. The electric potential difference across the plates is 160V. Point A is 2cm from the positive plate, point B is 3 cm from the negative plate.

-What is potential difference between points A and B

My attempt-

Electric field intensity: E=[tex]\Delta[/tex]V/d = 160/0.08 =2000N/C

[tex]\Delta[/tex]Va =E*d ---What value for d do i use?

[tex]\Delta[/tex]Vb =E*d ---What value for d do i use?

[tex]\Delta[/tex]Vab = [tex]\Delta[/tex]Vb - [tex]\Delta[/tex]Va
