field F 49. Eigure P15.49 shows a closed cylinder with cross-sectional area A2.00 m. The constant electric has magnitude 3.50 x 10 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 through the cylinder's a. top and b. bottom surfaces. c. Determine the amount of charge inside the cylinder. Figure P15.49 Answer +
