In a conductor, one or more electrons from each atom are free to roam throughout the volume of the conductor. Does this contradict the statement that any excess charge on a solid conductor must reside on its surface? Why or why not?

As a safety engineer, you must evaluate the practice of storing flammable conducting liquids in nonconducting containers. The
company supplying a certain liquid has been using a squat, cylindrical plastic container of radius r= 0.24 m and filling it to height h
10.2 cm, which is not the container's full interior height (see the figure). Your investigation reveals that during handling at the company,
the exterior surface of the container commonly acquires a negative charge density of magnitude 2.0 µC/m2 (approximately uniform).
Because the liquid is a conducting material, the charge on the container induces charge separation within the liquid. (a) How much
negative charge is induced in the center of the liquid's bulk? (b) Assume the capacitance of the central portion of the liquid relative to
ground is 41 pF. What is the potential energy associated with the negative charge in that effective capacitor? (c) If a spark occurs
between the ground and the central portion of the liquid…
