??-pr o at 11:59 pm (EDT) The fiqure belows shows two parallel plates. Assume they are infinite in area (this way we can neglect edge effects). The plate is at a potential of +40v and the plate on the right is at a potential of oV. The plates are a distance 24cm apart and the dashed spaced equally 6cm apart. L.

Explanation / Answer

since plates are very long so electric field will be constant between the plates direction of electric field will be from positive plate to the negative plates.

since we know that electric potential decreases in the direction of the electric field so

(1)the electric potential at point A is equal then the electric potential at point D.

(2)the electric potential at point D is greater then the electric potential at point F.

(3)the electric potential energy of proton at point A is higher the electric potential energy of an proton at point

C

(4)the electric potential energy of electron at point A is   lower the electric potential energy of an electron at point C
