1. A cylindrical metal can has a height of 27 cm and a radius of 11 cm. the electric
field is directed outward along the entire surface of the can (including the top and
bottom), with a uniform magnitude of 4.0 x 105 N/C. How much charge does the
can contain?
2. An insulating sphere with a radius of 20 cm carries a uniform volume charge
density of 1.5 x 10° C/m³. Find the magnitude of the electric field at a point inside
the sphere that lies 8.0 cm from the center.
3. A square metal plate with a thickness of 1.5 cm has no net charge and is placed
in a region of uniform electric field 8.0 x 104 N/C directed perpendicularly to the
plate. Find the resulting surface charge density on each face of the plate.
