3. A cylindrical metal has a height of 0.27 m and a radius of 0.11 m. The electric
field is directed outward along the entire surface of the can (including the top
and bottom), with uniform magnitude of 4.0 x 10°N/C. How much charge does
the can contain?
4. A square metal plate with a length of 0.20 m and with a charge of 9.7 x 10 -7 C.
Find the electric field of the square metal plate.
5. A uniform electric field E = 5000 N/C passing through a flat square area A = 2
m?. Determine the electric flux.
Note: The angle between the electric field direction and a line drawn
perpendicular to the area is 60°.
