Question
Figure 1 shows a configuration of a flat plane and an arbitrary shape, both carrying surface
charge density of magnitude σ. The arrows show the electric field lines. Are the statements

a) The flat plane is carrying a negative surface charge density −σ and the arbitrary shape is
carrying a positive surface charge density +σ. Justify your answer.
b) Both surfaces are equipotential surfaces. Justify your answer.

You may assume that the two plates are very large compared to the separation between the plates (i.e. you may treat them as 'infinite' planes). The plates are charged to ±Q, each plate has an area of A, and the plates are separated by a distance d. The x-axis in this problem is pointing from the negative to the positive plate, with the origin at the negative plate. The electric field at point 2 has a magnitude of E. E=3000 A=1 m² d = 8 mm c.
