Question

$10^6$ electrons are added to a pith ball. The charge on the pith ball will be

• A. $1.6\times 10^{-13}C$
• B. $1.6\times 10^{-19}C$
• C. $1.6\times 10^{-25}C$
• D. none of the above

Answer 1

Answer: (A)

charge on each electron is $1.6\times 10^{-19}C$
So the charge added = $1.6\times 10^{-19}C\times 10^6=1.6\times 10^{13}C$
