I need with these questions calculations

The figure below shows a closed cylinder with cross-sectional area A = 3.70 m2. The constant electric field E has magnitude 2.60 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 (In (N . m )/C) through the cylinder's top and bottom surfaces. HINT (a) top surface N - m C (b) bottom surface N - m (c) Determine the amount of charge (In C) Inside the cylinder. C Need Help? Read It Watch It13. [-/2 Points] DETAILS SERCP11 15.8.P.050.
