Question
(a) How strong is the attractive force between a glass rod with a $0.700 \textrm{ }\mu\textrm{C}$ charge and a silk cloth with a $-0.600 \textrm{ }\mu\textrm{C}$ charge, which are 12.0 cm apart, using the approximation that they act like point charges? (b) Discuss how the answer to this problem might be affected if the charges are distributed over some area and do not act like point charges.
1. $0.262 \textrm{ N}$
2. If charges are distributed, the resultant force between the objects would be the vector sum of each force on each charge due to the resultant electric field at each charge. Things would get complicated!
