The cylindrical imaging drum of a photocopier is to have an electric field just outside its surface of 2.00 105 N/C.

(a) If the drum has a surface area of 0.0610 m2 (the area of a 8 1/2 11 in. sheet of paper), what total quantity of charge must reside on the surface of the drum?

(b) If the surface area of the drum is increased to 0.122 m2 so that larger sheets of paper can be used, what total quantity of charge is required to produce the same 2.00 105 N/C electric field just above the surface?
