Demonstration: Faraday Ice Pail and Charge
Production
Since the Faraday Ice Pail is used so frequently in elec-
trostatic demonstrations, one should examine the rela-
tionship between the charge induced on the ice pail by
an inserted object and the actual charge on that object.
Using the ice pail, one can then investigate the nature of
charging an object by contact as opposed to charging by in-
duction.

Questions:
1. Look carefully at the figure 1 in which charge distribution at the pail is shown. Why do you
think the charge on the pail closest to the positively charged paddle is negative while the
opposite side is positively charged?
2. If one of the paddles carries a charge of 25 x 10-15C, what is the magnitude of the electric
field that you would expect on your hand if it is 2 inches away?

3. What is the magnitude of electric field due to a charge of 10 x 1012C at a point 9mm
away from it and what is its direction?
