The figure below shows the instant when a hollow metal box is
placed in a uniform electric field, and its effect on the external
field is not shown.
a. Indicate the electric charge distribution in the metal due to
the external electric field. Note: If electrons move from one part
of the box to another, the part with a deficiency of negatively
charged electrons is now positively charged, and the part with an
excess of electrons is negatively charged.
