Question
The figure belows shows two parallel plates. Assume they are infinite in area (this way we can neglect edge effects). The plate on the left is at a potential of +52V and the plate on the right is at a potential of 0V. The plates are a distance 24cm apart and the dashed lines are spaced equally 6cm apart.
Evaluate the following statements appropriately (less than,greater than, or equal to)
A. The electric potential energy of an electron at point A is _____ the electric potential energy of an electron at point C.
B. The electric potential at point C is ____ the electric potential at point B.
C. The electric potential energy of a proton at point B is _____ the electric potential energy of an proton at point A.
D. The electric potential at point C is ____ the electric potential at point F.
What is the electric potential at point D?
What is the magnitude of the electric field at point D?

A. The electric potential energy of an electron at point A is less than the electric potential energy of an electron at point C.
B. The electric potential at point C is less than the electric potential at point B.
C. The electric potential energy of a proton at point B is less than the electric potential energy of an proton at point A.
D. The electric potential at point C is equal to the electric potential at point F.
What is the electric potential at point D?
VD = (3/4) * 52 = 39 V
What is the magnitude of the electric field at point D?
ED = E = V/d = 52/0.24 = 217 V/m
