The electric field between two equally but oppositely charged parallel plates
is 2.35 N/C [south]. If a charge of –2.00 C was placed at the midway point
between the plates, what force (magnitude and direction) would act on the
charge? Give the direction as acting north or south.
c) For another set of parallel plates, a charge of –4.00 C experiences a force of
6.00 10–3 N [east]. Determine the magnitude and direction of the electric
field between these plates. Give the direction as east or west.
