The figure below shows a closed cylinder with cross-sectional
area A = 2.60 m2.
The upper and lower circular surfaces of a vertically-oriented
cylinder are labeled A. Electric field vector
E points vertically upward, going up through the
lower surface, up through the cylinder, and finally pointing up
through the upper surface.
The constant electric field E has magnitude
1.85 ✕ 103 N/C and is directed vertically upward,
perpendicular to the cylinder's top and bottom surfaces so that no
field...
