A figure shows a closed cylinder with a cross-sectional area A = 3.60 m2. The upper and lower circular surfaces of a vertically-oriented cylinder are labeled A. Electric field vector Epoints vertically upward, going up through the lower surface, up through the cylinder, and finally pointing up through the upper surface.The constant electric field has magnitude 2.85 ✕ 103 N/C and is directed vertically upward, perpendicular to the cylinder's top and bottom surfaces so that no field lines pass through the curved surface. Calculate the electric flux (in (N · m2)/C) through the cylinder's top and bottom surfaces. (a)top surface __________ N · m2 C (b)bottom surface  _______ NM^2/C (c)Determine the amount of charge (in C) inside the cylinder. _______C

In a CRT, after the electrons pass through the anode, they are moving in the z-direction at a speed of 8.40 x 10° m/s. They then pass between a pair of vertical parallel plates (A) and then between a pair of horizontal parallel plates (B). All four of these plates are squares 2.50 cm on a side. The plates of each pair are separated by 1.50 cm.The electric field between plates (A) is zero. As the beam exits the space between plates (B), it has been deflected 2.00 mm downward (Ay = -2.00 mm). In what direction is the beam moving now? Enter a positive value if the angle is below the horizontal and enter a negative value if the angle is above the horizontal.

A square metal plate of edge length 9.4 cm and negligible thickness has a total charge of 5.6 × 10-6 C. (a) Estimate the magnitude E of the electric field just off the center of the plate (at, say, a distance of 0.44 mm from the center) by assuming that the charge is spread uniformly over the two faces of the plate. (b) Estimate E at a distance of 39 m (large relative to the plate size) by assuming that the plate is a charged particle.

A uniform electric field of magnitude E = 38 N/C points along the x-axis. A circular loop of radius R = 26 cm is centered at the origin with the normal to the loop pointing θ = 45 degrees above the x-axis.   Calculate the electric flux in units of N⋅m2/C that passes through the loop.
