Question
Common static electricity involves charges ranging from nanocoulombs to microcoulombs. (a) How many electrons are needed to form a charge of $-2.00 \textrm{ nC}$ (b) How many electrons must be removed from a neutral object to leave a net charge of $0.500 \textrm{ }\mu\textrm{C}$?
1. $1.25 \times 10^{10} \textrm{ electrons}$
2. $3.13 \times 10^{12} \textrm{ electrons}$
